The Stories of Salt

Chapter 10 of my series, The Salt Bridge

My journey of discovery of the use of salt in southern Africa brought me to Johannesburg. Minette and I wanted to be in New Zealand but dubious former business partners had other ideas.  The Universe used the bad intentions of my previous compatriots and predestined me to be in Johannesburg.  I went hiking around the country to find the soul of this land.  Suddenly, quite unexpectedly, out of the bush appeared three tribes.  One of these tribes, in particular, took me in and started showing me amazing things.  Salt itself started talking to me and took my journey further.

I scarcely landed in Johannesburg when I did the 14km hike at the Suirkerbosrand reserve just outside Heidelberg.  I completely missed the many old stone ruins.  Back home I read up on the site and discovered that a huge Twana settlement was located there.  I was back the next weekend and then I found the ancient village!

Massive South Tswana Village at Suikerbosrand (Heidelberg, Gauteng)

 

I saw the ruins of an impressive Tswana mega-city close to the modern-day town of Heidelberg.   At Suikerbosrand there is an ancient Tswana city. It turns out that roughly built stone structures can be seen in several locations throughout the reserve.  Over the next weeks, as I kept returning to the site, I came across many more structures.  Archeologists discovered pottery designs and other objects such as copper ornaments, iron spears, iron rods, and hoes, which identifies the inhabitants as Sotho-Tswana. The such South-Tswana settlements were present throughout Gauteng.

Judging by the dated architectural styles that were common at Suikerbosrand, it’s estimated that the builders of the stone-walled structures occupied this area from the fifteenth century AD until the second half of the 1800s.  The biggest cluster of circles on the reserve form part of a much larger settlement, with what appears to be a royal kraal with commanding views of the surrounding area.

Using recent laser technology (LiDAR), researchers were able to recreate the remains of the city. The evidence gathered by researchers from WITS university suggests that the area was certainly large enough to be called a city measuring nearly 10km (6.2 miles) long and about 2km wide.”

Here is a reconstruction of what it may have looked like, built from the results from the LiDAR research.

Parys on the Vaal and the farm of Berakah Eco Trails

Since I am close to Parys, I thought there may be great hiking trails.  Johannesburg itself is notoriously scarce in its offering to outdoor enthusiasts!  I drove to the Northen Free State town of Parys to try a new area.  I googled “hiking trails” in the area while sitting at a coffee shop in Parys and I could find only one, on the farm where Berakah Eco trails is located.  No sooner did I start the hike when I came upon another massive settlement.  By this time, I have come across a huge Twana site in Suikerbosrand and now, completely unexpected, the ruins on the Berakah farm on the Vaal River.

 

The Tswaing Salt Lake in Soshanguve, north of Pretoria

I was looking for a transition to enter the Gauteng region in the book I am writing on the history of meat curing.   I wanted to link my time in the story riding transport between Johannesburg and Cape Town to my quest for the origins and use of salt in southern Africa.  I was looking for possible locations where bicarbonate of soda naturally occurs which I thought would do the trick very nicely as a transition salt into my much detailed look at sodium nitrate and nitrite, ammonium chloride and sodium chloride in “Bacon and the Art of Living”.  To my great surprise, I found that high levels of bicarbonate of soda occur abundantly in Tswaing salt lake, 40km north of Pretoria.  The site is, at the same time, one of a handful of impact craters in southern Africa.

Here I discovered more ancient ruins at the impact crater which was in all likelihood connected through trade to the communities in the Suikerbosrand, the communities along the Vaal River and definitely connected to the people who lived in the Magaliesburg region.

 

Twana Ruins on Eastwick

As I was discovering the Tsana cities at Suikerbosrand and the sites close to Parys on the banks of the Vaal River, their important salt source of Tswaing; while salt was leading to the local tribes, I discovered the Magaliesberg sites.  This region was introduced to me by Etienne Lotter who has his farm, Eastwick Stud Farm, here where they have one of the best Nguni herds on earth.  Soon after my hikes in Heidelberg, along the Vaal River and north of Pretoria, I visited Thys and his wife on the farm and hiked to the top of the cliffs of the Magaliesberg mountains up a gorge on Eastwick. At the top, we discovered the old ruins of a large indigenous village.

The Magic of Salt

I was intrigued!  The complexity of the societies, their close interconnectedness – their size and sophistication, it all blew me away!  I realized that my quest for understanding the use of salt in southern Africa is nothing less than hearing their stories, told to me by the elders of the different villages, while we sit at the evening village fire, and eat their sumptuous dishes.

Salt is the medium that can not be understood without understanding the people who enjoyed it!  I had to learn about the people so that I can understand what salt is telling me.  THAT is my first lesson.

What will follow are the stories of salt, and we begin with the story of three tribes!

The impact of Sodium Bicarbonate and the Twaing Impact Crater

The impact of Sodium Bicarbonate and the Twaing Impact Crater

Introduction

There are many ancient salts on earth. Over the years of studying many of them, I discovered a unique and fundamental property. They are alive, able to speak, reason and will!

They direct me in my everyday work at the deli meat producer in Johannesburg, Van Wyngaardt. They commune with me at night when I sleep. They do not let me rest, directing my thoughts and inquiries. The spirit of ammonia, spirit of saltpeter, spirit of sal ammoniac, spirit of soda ash, spirit of soda; these collectively form the Spiritus Mundi, literally, the World Spirit, which, in the interpretation of Yeates, contains the collective soul of the universe, the repository of the memories of all time.

Salt and the peoples of Southern Africa

Crosscurrents converged. For years I have been studying salt from the perspective of the people of Southern Africa. I took some time during two long visits to New Zealand to study the ancient salt production in that country and expanded it to Polynesia and touching on Taiwan and China to gain a better understanding of the regional technology related to salt. I became convinced that even if there was no actual salt production in pre-colonial New Zealand, that this does not mean that the Maori did not have a sophisticated knowledge of salt, as did the people from the region it finds itself in.

Back in South Africa, I fell in love with another great African technology of cattle breading when I was introduced to the subject of the Nguni by Etienne Lotter. It is the Nguni cattle which in turn lead me to the great indigenous cultures of sub-Sahara Africa and I started seeing these people, not as primitive humans, but very sophisticated societies.

I was trying to imagine apart from sodium chloride, what salts would the peoples of southern Africa have encountered and then, more importantly, what did they use it for. The most obvious answer for me, apart from sodium chloride, was to start with bicarbonate of either sodium of calcium.

Sodium Bicarbonate

Calcium bicarbonate was a logical starting point due to the existence of so many limestone caves in Southern Africa. My own exposure to caves taught me that stalactites and stalagmites form in limestone caves. Limestone contains at least 50% of calcium carbonate which dissolves in water. The water, in turn, contains carbon dioxide. Calcium bicarbonate is formed and the reaction is represented as follows:

calcium carbonate in water with carbon dioxide

The water with the calcium bicarbonate travels through the ground to the roof of the cavern where it comes into contact with air and a reaction takes place that creates calcium carbonate again which is deposited on the cave floor or suspended from the ceiling forming either stalagmites and stalactites. The reverse reaction where the calcium carbonate is created is represented as follows:

calcium bicarbonate to calcium carbonate.png

We are familiar with the effects of calcium bicarbonate in hard water where buildup is caused in one’s bathroom or kitchen and is difficult to clean. In limestone caves, the white calcium buildup is seen everywhere and these would have been tested by the industrious Africans. The custodians of chemical technology in Africa, as in probably all parts of the globe, was at some point the domain of the Sharma and healers. The white precipitate in the caves would have been heated, burned, rubbed onto wounds, tasted, used in foods, in water, in drinks and part of various potions and purely based on observation and by elimination, the properties of the salt would have been elucidated.

Calcium carbonate and calcium bicarbonate in terms of food preparations and preservation would not have done much. The only place on earth where I could find calcium carbonate or bicarbonate being used in food preparations is in Korea. Sodium bicarbonate, however, is a completely different story. I knew this from my work on another great African salt, Natron.

Natron

Natron contains around 17% sodium bicarbonate (NaHCO3). The other chemical present is sodium carbonate decahydrate (Na2CO3·10H2O, a kind of soda ash) and a small quantity of sodium chloride and sodium sulfate. I was first alerted to the preserving power of Natron when I realised its role in embalming. (Salt – 7000 years of meat curing) It is not hard to guess the extreme effective nature of sodium bicarbonate in preservation.

Corral, Laurie, Thomas, and Montville (1988) published a key paper on the use of sodium bicarbonate in meat preservation, Antimicrobial Activity of Sodium Bicarbonate.

I, myself, started using it with tremendous effect as a meat preservative. I wondered if there is any place in Southern Africa where sodium bicarbonate naturally occurs.

IMG_20190622_093933

Twaing Impact Crater

Of course, it occurred naturally wherever Natron was found, but what about Southern Africa? To my great surprise, one of the very few places sodium bicarbonate naturally occurs is at a very special site, 40km’s North of Pretoria called Twaing. It means “the place where salt is.”

Around 220 000 there was an event where a meteorite struck the earth at this site. It exploded and vaporized on impact and the impact craters and the salt lake was formed.  The small groups started visiting Twaing between 130 000 and 30 000 years ago after the plant life was restored and animals returned to the region following the impact event. These groups came here to hunt, gather plant to eat and use for medicine and, of course, to collect salt. They made stone age tools and weapons. Scrapers, points and stone tools that were thrown away were found at Twaing. None of the rocks at Tswaing is suitable for making such tools and points, showing that these objects were brought from somewhere else. Interestingly enough, there were also artifacts found at Twaing that is smaller than the ones from the Middle Stone Age which we just referred to. This may indicate that the ancestors of the San Bushman who lived from 30 000 to 2000 years ago visited the site during a time known as the Late Stone Age.

The first ancestors of the current indigenous people, the first farmers to use iron age tools, migrated to South Africa 1850 years ago. The first Iron age people came to Twaing around 800 and 900 years ago. Decorated clay pot fragments found on the crater floor shows that these people were Sotho or Tswana speaking communities known as the Miloko who used the salt to preserve and flavour food and trade with it. It shows that by and large, people did not stay very long at Tswaing. It seems that most people who came to the crater was periodic visitors from the Waterberg area (and other locations). So far they have only found one Iron Age community at Tswaing along with a grindstone, decorated and undecorated potsherds.

There is evidence that the salt they collected was used for flavouring, food preservation, and trading. A large number of undecorated potsherds found in the crater indicate shows that Tswana and Sotho speaking people made up most of the visitors until the advent of the time of the Matabele in the 1820’s.

In the 19th century, factors such as drought, famine, competition for grazing, wood, and water and trading routes precipitated tremendous unrest and conflict between the Iron Age Inhabitants of South Africa. New political groupings were formed and new kingdoms emerged and militarism grew.

One such empire was the Ndebele (Matebele) empire. They established themselves north of the Vaal River in the early 1820’s. A band of Nguni refugees under Mziklikazi from KwaZulu-Natal started attacking and defeating Sotho tribes. In 1827, the kingdom relocated to the Magaliesburg region. From there they launched attacked and conquering Tswana/ Sotho chiefdoms to the North and West. It has not been proven, but it is very possible that the Matebele visited Twaing to collect salt and hunt the many wild animals who congregated there.

For most of the 19th Century, Tswaing remained the key salt lick north of Pretoria. Large herds of game gathered here including elephants until the early mechanized salt mining operation scared them away.

Tswaing: Sodium Bicarbonate and an Impact Crater – a massive impact

On Saturday, 22 June I visited the Tswaing impact crater and salt lake. I set off with a guide on the roughly 7km hike on the crater rim. In the first video, I arrive at the salt lake and impact crater.

Arriving at the water’s edge. The boreholes were drilled as a means to extract the salt brine. The taste of the salt is amazing! It has a depth in taste that surprises you! It is less salty than one expects and the aftertaste is exquisite!

Sampling the salt and the background of the salt.

What was it like arriving at the site 200 years ago?

Conclusion

The impact of the crater has been profound. The knowledge of the ancients was impressive and their technology sophisticated. Sharing the space and knowledge possessed by the ancients is one of the highest privileges on earth! It was fantastic being here and continuing to understand the implications of this site.

Project – Legendary Foods

8 June 2019
Project Legendary Foods
Eben van Tonder

Introduction

I moved to Jhb for work three months ago.  I joined a very special company called Van Wyngaardt.  The mission of the company is very simple, to create legendary foods and our pay-off line, created by Etienne, is “Exceedingly Good Meat.”

A massive Tswana City on Suikerbosrand

Last weekend I did a 12km hike at the Suikerbosrand Nature reserve 60km outside Johannesburg, past Heidelberg on the way to Durban.  I was browsing the web for interesting information on the area and learned of a massive Tswana city which was located here. I made contact with Talfrein Harris whos friend, Stephen Banhegyi, worked on the site for his master’s thesis.  They could not take me out to the site this weekend, but I was back early this morning to see what I can find.

As I hiked up a path this morning, I suddenly realized that I was on the edge of many of the stone structures.

From my reading on the web, I learned that the city was massive!  10km long and 2km wide. By comparison, Mesopotamia was only 2km in diameter. Friday evenings I am watching on Discovery how new technology, called Lidar is used to see through the vegetation using laser lights which helps researchers to recreate the world of the Maya civilization.     The exact same technology is being used at the site on the Suikerbosrand.

There were many large Tswane cities scattered along the northern parts of South Africa until the 1820’s when they collapsed in the Difeqane Civil wars.  Archeologists use the building style to estimate its creation around the late 1400’s AD the city is believed to have been abandoned around the second half of the 1800s with between 750 and 850 homesteads in the city.

The ancient homesteads at Suikerbosrand are shown against an aerial photograph from 1961. The two rectangles show the footprint of the LiDAR imagery. Karim Sadr

As I moved up the hill and was suddenly right in the middle stone walls.  I was thrilled and the best thing about it all is that I have a little insight into how they ate their meat.  Yesterday I discovered a quote by Lichtenstein that confirms the practice of Southern African tribes who used ash as salt.  It is in reference to Tswana people in the northern Cape area and he wrote about them that “salt properly, they have none; instead of it they make use of natron, or the ash of a certain salt succulent plant: their favourite mode of dressing their meat is to roast it in the ashes.” (Lichtenstein, 1803)  We will return to his reference to natron which certainly does not refer to natron from the Natron valley in Egypt.  The primary interest is his reference to salt from ash. I have been researching salt and the ancient people of South Africa for years and I know how they cooked their meat! My intention is to recreate it as closely as possible.

In Johannesburg, I joined the only company in South Africa who allows me and the amazing team working with me to te recreate these legendary dishes.  The intention is not just to do that but to recreate local dished with local ingredients, inspired by the greatest fermented, cured, and smoked products.  We want to make hams and salamis and bacon according to many years of German and Italian, Spanish, Dutch, Danish and English traditions, but marry it with the richness of the South African cultures and we want to incorporate into it, the arts of cooking from Africa!  Besides processed meat, we want to celebrate great South African cattle breeds by making traditional Afrikaans and South African dishes from the best meat created by many years of evolution and careful breeding, right here in our own land.

The section I am starting today is intended to house our research projects and feature our best creations.  There will be old favourates like biltong, droe wors, bacon, and salami, but this will only be the start.  We intend creating legendary hams and other cured and fermented products with local flavours and using our local climate to do most of the work.

Legendary!  Insanely legendary!

Mild Cured Bacon – Recreating a Legend

Invention

Irish Mild Cured Bacon was invented by Mr. William Oake of Ulster sometime in the late 1820s/ early 1830s. Mild cured bacon was the first technical development away from traditional dry cured bacon that was practiced for millennia. It was replaced by the modern high injected, industrial bacon following World War 1. The use of needles to inject brine into the meat tissues was incorporated into the system very early on. Needle injection itself was invented in c. 1850, also in Ireland.

Original Method

Brine was prepared and sterilised. Meat was soaked in liquid brine for 7 days. After brine soaking, it was rested for up to three weeks and smoked. Smoking was done for between 24 and 48 hours.

The simple brine make-up was:

10 lb salt (54%)
8 lb of dark brown sugar (43%)
1/2 lb of saltpeter (2.7%)
Total brine: 18 1/2 lb. (100%)
Dilute it in water, but it must be able to float an egg.

Recreating a legend

In 2019, I joined a unique company in Johannesburg. They gave me the opportunity to recreate Mild Cured Bacon and we are making it available to a carefully selection of retail outlets and catering clients.

Product Features

Irish Mild Cured bacon is an excellent example of traditional methods, natural ingredients and a pure meat product, unadulterated by modern influences.

Recreating a Legend

The first step was very successfully tested wit the expert help of Carlo and Stephen at Van Wyngaardt on 16, 17 and 18 May 2019. The four week period was reduced to three days for testing purposes but the process steps were retained. The results were spectacular.

The brine composition was retained with the exception of the salt and saltpeter quantily which is reduced to much lower levels. Sugar levels are also reduced to prevent burning in the pan due to excessive caramelisation. Ascorbate, a natural product, is added to comply with legislative requirements.

The next phase is to adjust the time closer to the original. As it is, what we created is EXCEEDINGLY good meat!

Superior in Every Way

Newspapers started tracking the price of Mild Cured Bacon from 1842. It shows the place it occupied as superior to any other system and its legendary status. Mild Curing was finally abandoned after the First World War when it was replaced by quick curing, high volume, high injection modern bacon processing methods. It is safe to say that following the war, apart from small artisan operations, it, by and large, disappeared until our recreation!

Here are a few quotes about it followed by the actual article or advertisement.

Conclusion

The grandeur and magnitude of producing these legendary foods cannot be overstated. Being involved in the project is an honour. Modern demands of “lower prices” has chipped away at the heart of what made bacon from the late 1800s EXCEEDINGLY great! We are delivering on a vision to put EXCEEDINGLY good-ness back into meat!

Nguni: Living Works of Art

Introduction

IMG-1849-EFFECTS

Cattle are ancient, magical, living works of art.  Antjie Krog in her book Change of Tongue writes: “In Setswana, cattle are known as modimo o nko e metsi – god-with-the-wet-nose…. On Saturday I spent the afternoon with the kids among one of the greatest Nguni herds on earth, at Eastwick Stud Farm of Etienne Lötter, managed by Thys Koen.  I have been reading about their origins and followed their ancient migration routes into West and Southern Africa.

Here I will look at what it takes to breed great cattle but they are more than just a technical consideration. A poem is, therefore, a great first look at them.

IMG-3705-EFFECTS.jpg

Nguni Herds

Margaret Epstein
Translated from the Afrikaans by the poet

Nguni herds
shift silently as spirits
Across the face of the earth.

Back and back they go,
generation upon generation
through Africa’s history,
forming a bond between man and beast.
Reckoned in honour,
pride and wealth.

To reflect an eternal
forming and dissolving pattern
of shadows and sunlight,
mud, pebbles, rocks
and grains of sand.

In the silence of heat,
under thorn tree branches,
alongside pools of water and cliffs,
across centuries
the sound of bellows,
the blowing of cattle breath
and voices calling,
echo through a haze of dust.

Spoor of cattle and men
lie stretched out over plains
and mountains.
Their marked skins and graves,
eternal signs of temporary ownership,
are alone and deserted,
lost, disintegrated in the veld,
forgotten.

Now we stand
in this time and place,
to admire Nguni cattle, their distant past,
innocence and patience,
patterns of spots, horns, blemishes
and intimate family conversations.

Remember the old links,
but loosen the bridle
of today’s constraints.
Free your thoughts to wander with us,
to dream.

Introduction

The quest to understand how great bacon is made takes me around the world and through epic adventures. I tell the story by changing the setting from the 2000s to the late 1800s when much of the technology behind bacon curing was unraveled. I weave into the mix beautiful stories of Cape Town and use mostly my family as the other characters besides me and Oscar and Uncle Jeppe from Denmark, a good friend and someone to whom I owe much gratitude! A man who knows bacon! Most other characters have a real basis in history and I describe actual events and personal experiences set in a different historical context.

The cast I use to mold the story into is letters I wrote home during my travels.

Dr. Polenski

April 1891

My dear Son,

the_noord-nieuwland_in_table_bay_1762
The Noord Nieuwland in Table Bay 1762

Since my last letter about the city and the food, the strange shops, elevated above the streets, the beer and the warm people, I realised that the culture of this amazing land is having just as big an impact on me as what I am learning about the curing of bacon.  I wrote Minette two letters in which I laid out how unbelievable it is that I came to this land first who adopted the Irish system of curing and took it to new heights by combining it with their powerful and unique cooperative model!  Andreas gave me a word of caution that knowing the steps of a process and understanding the process are two different things. No sooner did I hear those words when the ever-resourceful Jeppe presented me with the next gold nugget.

After supper, at the Østergaard home, we follow another tradition of this knowledge hungry people and read together and discuss what was read.  This is customary in many households. The Danes have a  practicalness about them.  As I have seen from their unique high school model, they never stop learning and if something works, they adopt it.

Every night after supper, Andreas’ dad reads for us from a book called Foods, written over 20 years ago in the 1870s by an Englishman, Edward Smith.  He helped me to see the curing of meat as both a necessity and a delicacy.  We cure meats because, for the most part, using modern curing methods, cured meat tastes great.  On the other hand, meat curing was started to impart longevity;  to prevent spoilage.

Back home we are of course well familiar with the value of meat that “last.”  In Europe and England with their growing populations and vast navies which have to be fed, it has been an obsession and a priority to solve the problem of conserving meat for future use.  Edward Smith says in his book that “the art of preserving meat for future use, with a view to increase the supply and lessen the cost of this necessary food (meat), is of very great importance to [England] and all the available resources of science are now engaged in it.” (Smith, 1876: 22)

He lists the main ways that this is being done as “by drying, by cold, by immersion in antiseptic gasses and liquids, by coating with fat or gelatin, by heat, salted meat and by pressure.” (Smith, 1876: 22 – 38)  All have their benefits and disadvantages and I have a feeling that over the years, the technology within any one of these groups may develop, but these broad categories will remain and continue to be available to the public.

Edward Smith says that pork is particularly prized over beef and mutton because of the  “taste, but chiefly perhaps [due] to the universal habit among the peasantry of feeding pigs, which has descended from Saxon times.  Moreover, there is a convenience in the use of it, which does not exist with regard to beef and mutton, for in such localities the pork is always pickled and kept ready for use without the trouble of going to the butcher, or when money could not be spared for the purchase of meat.”  Pigs proved to be an equally prized meat in the new world due to the “ease with which pigs are bred and reared, and the meat preserved, whilst there is great difficulty in obtaining a sufficient number of persons, in a thinly populated country or a small village, to eat a sheep or ox whilst meat is fresh.  (Smith, 1876: 59)

“Bacon is made when cuts from the pig are preserved by salt and saltpeter.”  (Smith, 1876: 64).  This gives bacon its characteristic pinkish/ reddish colour, a nice flavour, and it lasts a long time before it tastes “off”.  This is the kind of things we learn at night.  After a good supper, we discuss what has been read for an hour or two before retiring to bed.

In the day I work at Uncle Jeppe’s cooperative bacon curing factory.  I started working in the curing and spice department where we mix herbs and spices.  Uncle Jeppe is a knowledgeable man and it seems as if he has been around in the meat industry forever.  I have not asked him any question that he did not know the answer to.

Take saltpeter for example. It is the curing salt for bacon which I work with every day in the curing department.  When we do dry curing, we use 1.25 st. (10 pounds) salt, 0.375 st. (3 pounds) of brown sugar, 0.04 st. (6 ounces) of black pepper and 0.02 st. (3 ounces) of saltpeter.  We use 1.25 st. (10 pounds) of this mixture per 12.5 st. (100 pounds) of meat.  (1, 2, 3)  The Irish system of mild cured bacon calls for a liberal use of saltpeter and the purer form of sal prunella. This is the main curing system we use and in both dry curing and tank curing (as mild cure is also called), it is a key ingredient.

What confused me much about saltpeter was that Trudie’s dad, Anton, also talks about the value of phosphates and saltpeter in fertilizing their fields in the Transvaal.  I have learned in school that saltpeter is one of the ingredients in gunpowder.  I know that the Dutch East Indian Company was created, in part, for the purpose of transporting saltpeter from India to Amsterdam and other European cities like Copenhagen for fertilizer and to make gunpowder. I always wondered if it is the same substance that is used to cure meat and if it is, how can this one substance be useful for such diverse applications.

I asked Jeppe about saltpeter one morning.  He put his arm around my shoulders and told me that there are interesting answers to these interesting questions.  That he hopes I paid attention in chemistry class in school.  For the next week, our Tuesday and Thursday afternoon classes during lunch break were dedicated to saltpeter.

The power of saltpeter is the fact that it contains nitrogen and nitrogen is one of only two elements, with carbon, that can exist in 8 oxidation states.  This means that nitrogen can react in a diverse and complex way and, like carbon, is foundational to all of life.  The two substances that contain nitrogen, most familiar to us, are saltpeter and ammonia.

The nitrogen in saltpeter and ammonia makes it very reactive, giving it an explosive power.  In saltpeter it has a particular effect on blood, explaining the fact that it gives cured meat its pinkish/ reddish colour.  Nitrogen exists in the first place as a gas in our atmosphere and comes into our world in different ways, the most important being through microorganisms with the ability to take it from the air and convert it to food for plants.  The plants take these compounds from the soil and water where the bacteria lives and nitrogen become part of the plant’s structure.  This is why saltpeter is a great fertilizer.  It is plant food!

Uncle Jeppe will tell me the fascinating story of how this was discovered but he said I had to be patient to hear this another day.  I am here to learn the modern way of curing bacon.  In Europe, I find myself right in the middle of the most up to date and advanced thinking about curing.

I know the steps and benefits of the Irish system, but science is only now unlocking the “why?” and “how?” behind its power. A major step has been taken in understanding the speed and better consistency in mild curing when compared with dry curing when a friend of Uncle Jeppe discovered something remarkable.

His friend’s name is Dr. Ed (Eduard) Polenske (4), a chemist, working at the Imperial Health Office in Germany.  Jeppe tells me that 1891 will forever be remembered as a watershed year for Woody’s since it is the year I arrived in Denmark and started learning about bacon curing; for the curing industry in South Africa since it is the year when Woody’s took the first steps to excellent bacon in Africa; and for the curing industry around the world because of Ed’s discovery.

It is the year when he made a startling discovery that brine and cured meat contain nitrite. This is remarkable since we know that saltpeter does not contain nitrite, but nitrates and we only use saltpeter in curing of meat which begs the question as to where the nitrite comes from.  Even though nitrite and nitrate are spelled almost the same, in reality, these are two completely different compounds with different characteristics.  Despite the fact that we do not add nitrite to the meat, how does it get there?  It is also a fact of great concern because nitrite is very toxic.

So, before Uncle Jeppe learned about Dr Ed’s findings in 1891, what we knew is that only saltpeter or nitrate is used to cure meat.  We also know that the Irish system of curing compared to dry curing cures the meat much faster.  This matter of the speed of curing is important.  Dry curing is accomplished in 28 days where mild cured bacon can be produced in 19 days. On farms, long curing is generally not a problem, but for a commercial curing operation, it means that you keep large stocks of bacon that are in the process of curing. If you produce bacon for household consumption, that is one thing, but when you have an army to feed, speed is of the essence.  Speed to the modern curer is key.

Jeppe and Ed met up in Wiesbaden, Germany, earlier this year.  This has been an annual winter ritual when the two men took their annual retreats at the same time.   They became acquainted at the  General Congress on Hygiene in Brussels in 1852.  It is exactly the hygienists that Dr. Ed fears will be most concerned about the fact that he found nitrites in cured meat.

Both men attended the conference and struck up a friendship based on their shared passion for good quality and safe meat.  Wiesbaden is famous for it’s hot springs since ancient Roman times and the second shared love between these men, besides meat technology and science, is their love for hot springs.

They have been hosted each year by an equally interesting man, Francois Blanc, at one of his gambling resorts in Wiesbaden.  It is said that he is the man who made Wiesbaden what it is today.  Jeppe describes Blanc as a mighty wizard with an eye, quick to see the possibilities of a situation, with a brain to plan and a hand to execute.  His ambitions and achievements are great across Germany, yet, Jeppe tells me that his tastes are simple.

His clothes do not attract any attention and he wears his spectacles on the tip of his nose.  He does not pay attention to flattery, yet, he is a hard-headed, silent man without any enthusiasm and equally without any weaknesses.  He keeps lavish tables, yet he himself eats sparingly.  His wine cellar rivals those of the autocrats in Russia, yet, he himself only drinks mineral water.  He is one of the largest gambling hall owners in Europe, yet, for entertainment, he may occasionally play Dominoes and frequently goes on a drive through the countryside with his wife.

It was at their annual visit to Wiesbaden, earlier this year, where Dr. Ed told Jeppe about a monumental discovery.  Dr. Ed is not a huge fan of cured meat since in producing it, nutrition is lost.  That is, of course, especially true of dry cured meat. The new Irish system largely overcomes this by filling the tank with liquid brine. The partial pressure difference between the meat and the brine has the effect that instead of drawing the albumen out of the meat, as is the case in dry curing where the meat is only rubbed with salt, in the mild curing technique, brine seeps into the meat. No albumen is lost. But for the most part, dry curing is practiced with an accompanying loss of nutrition. At a time when most families across the world can not afford to eat meat more than two days a week and where most children go to bed hungry, at least a couple of times a week any loss of nutrition is a problem in any food source. In the current world context, Dr. Polenske believes the most important consideration in evaluating methods of preservation is its effect on the nutritional value of the preserved food. He is obviously not very familiar with the Irish mild cure and in his work, he mainly considered dry curing.

He designed an experiment to study just how much nutrition is lost.  The brine he prepared was a combination of salt, sugar, and saltpeter.  (5)  He put this in three jars with three pieces of meat which he sealed and opened again after 3 weeks, 3 months and 6 months respectively.  When he tested for nitrite, he unexpectedly found it in the brine and the meat, despite the fact that he did not add any. (6)

Dr. Polenske told Jeppe that he was not that surprised to find nitrite in the brine since he knew that saltpeter is a compound of potassium or sodium nitrate.  Nine years earlier a drama unfolded with a discovery by French scientists of bacteria that changes nitrate into nitrite and further into nitric oxide.  In 1882 a team of researchers, Ulysse Gayon from the French commune or town, as we call it, Bouëx in Charente and his 22-year-old collaborator, Gabriel Dupetit, from the town of Auch, Gers, coined the term denitrifying bacteria.  This formidable research team went on to make a number of very important discoveries about denitrifying bacteria. (7)

Nitrification starts with nitrogen gas which is one of the most abundant gasses in our atmosphere and through the nitrification process, bacteria create more complex compounds such as nitrate (codecogseqn-2).  An example of nitrification is ammonia (codecogseqn-7) which is changed into nitrite (codecogseqn-5) and finally into nitrate (codecogseqn-2) which serves as the nutritional source for plants.

Denitrification is the reverse where a more complex molecule is broken down to the point where it ends up with a simple molecule like nitric oxide (NO) or pure nitrogen gas (codecogseqn-6).  Denitrification is, therefore, the reverse of nitrification.  This time it starts with a complex compound of nitrate (codecogseqn-2)  which is changed into nitrite  (codecogseqn-5), into nitric oxide (NO), into nitrous oxide (codecogseqn-8) and finally back into nitrogen gas or molecular nitrogen (codecogseqn-6).  Note the gain or loss of the oxygen atom in both processes.

Louis Pasteur, the renowned French chemist, and microbiologist urged Gayon to follow what happens with the oxygen of the nitrite utilised in the process of denitrification.  They heeded his advice paid close attention to this.  They conclusively refuted an old notion that nitrate was reduced through chemical means by the hydrogen, generated during fermentation.  As to the purpose of the loss of oxygen they believed that the bacteria used the oxygen from nitrogen for the combustion of organic matter to generate  CO2. (8)

Based on their very thorough work, Dr. Polenske believes that nitrite is present through this process of denitrification of nitrate by bacteria.  He expects there to be much public concern following his discovery since nitrite is seen as a poison.  (9)  There is a constant battle from farmers to keep their cattle away from water that has nitrite and in every major newspaper, in every town and city, the nitrite levels in the town’s drinking water are published every week so that citizens know to avoid it.”

Jeppe was now becoming particularly excited. “Eben,” he said and put his hands around my shoulders. In his other hand, he had a pen and started drawing a picture for me on a blank piece of paper on his desk.  “In dry curing we start with nitrate. Sodium or potassium or calcium or magnesium nitrate, depending on where you harvest the nitrate from. We now use it to mix into salt and rub it on the meat to cure in dry curing. What is happening?”

I told him that the nitrate will be turned into nitrite by bacteria. “Yes, yes, yes!” He said impatiently. “But what else? What do you see?” Still, I had no clue what he was talking about.

“Time!” He exclaimed, “It will take time!”

“What is the faster process? Dry curing or mild curing”, he asked.

That one I gladly knew. “Mild curing!” “Correct!”, he exclaimed. “Correct!” “But why?”

Suddenly I saw what he was driving at! “The time it takes the bacteria to convert the nitrate to nitrite . . .” “And what?”, he spurred me on. “What does this points to?” “What is doing the curing?'”

I suddenly saw it and it a bolt of energy hit me. “It is the nitrite doing the curing and not the nitrate!” “The time difference between the old system of dry curing using nitrites and the new system which re-uses old brine is that in the old brine, the nitrate is converted to nitrite! This is the power of the old brine! This is why it is so much faster!”

His secretary walked in at that moment announcing that his next appointment is there. “Oh, let him wait”, Uncle Jeppe exclaimed! “”Get us coffee! There is some hope for South Africa after all!!” He gave me an enthusiastic slap on my back!

“Exactly!”

“Exactly!”

He walked around his desk and sat down. “This I did not discuss with Polenski but I saw it immediately! If I told him the entire Germany would convert to mild curing and Denmark’s competitive edge would be lost.  I sat there thinking of what Andreas told me. That I will find that my greatest discovery won’t be the mild curing process, but why it works the way it works. The “why?” And “how?” of curing. I was exhilarated! Like last Friday when I learned about mild curing and the Danish Cooperative model.

Tristan, I know you love biology and the natural sciences. This is why I address this mail to you and I have no worry that I become too technical. The reaction sequence and mode are beautiful. I can honestly say that I am completely in love with the natural world.

I now want to know every element present in the brine, and its exact function. What is the chemistry in the meat itself?  How does curing happen? When we know this, we will be in a position to manipulate the process and improve on it.

My son, you know me; that there is another important point in this story that strikes me.  Right at the start of this journey, I realised that what we are discovering is much more than simply learning how to cure bacon.  This journey back to the lands of my forefathers is a big deal! In a way, it was already an end in itself for me. History and context if of enormous importance. Our lives are never in isolation. We come from the soil of Denmark and the fact that it is here where I find the answers is hugely important to me!

Besides this, bacon is in the center of scientific research of Europe, America, and the United Kingdom, and the combined scientific focus of these countries are directed at unlocking its secrets which are bound up with that of agriculture and superior technology in warfare.  Besides these, there are the many human stories that are part of the story of bacon.  Real people who each contribute to small parts of a very large jigsaw puzzle that is coming together.  They teach us about life. We do not live in isolation, my son! What I am recounting is not fiction! I tell you real stories of real people! Let us pause right here and think about this truth! It is deeper than bacon!

Within the same year of publishing a major paper on denitrifying bacteria by Gabriel and Ulysse, tragedy struck.  The young Gabriel Dupetit’s tragically ended his own life.  He traveled to the Italian city of Savano and booked in at the Albergo Svizzero under the false name, Gaston Dunault.  Overcome by anxiety of all sorts, on the evening of 28 December 1886, he injected poison into himself.  He was discovered, barely alive and despite much effort to save his life, he passed away on the morning of the 29th.  He left a note in French explaining some of his worries.  The use of the false name was done to hide his identity and spare his parents embarrassment.

I am humbled and saddened by this story.  His work directly contributes to our quest of understanding bacon and still, his death reminds me that our lives are bigger than our goals and dreams.  Despite our ambitions, we must pay attention to each sunset and sunrise and never make the mistake of thinking that achieving goals define us.  A man who got this balance right, I believe, is Francois Blanc who seems to find fulfillment in small things, despite his success.  His success does not define him.  He finds the greatest fulfillment in the ordinary in life.  In this, bacon and life become inseparable and I am never sure when I stop learning about the one and start learning about the other.

Maybe, I wonder, the biggest and most important acts of his life was the drives he took through the countryside with his wife. His relationship with his sons and the evenings that Uncle Jeppe and Dr. Polenski spent with him of which Uncle Jeppe tells me that Blanc was really happy.

We don’t understand any of the processes, but identifying the different elements in the brine, including microorganisms, nitrate, nitrite, salt, potassium, and sugar is the basis for understanding the process and should open up the possibility to do it faster and better and safer system without losing quality.  I would love to take back to Cape Town a curing method where curing can be done in a shorter time than 19 days, yielding a product that tastes just as exquisite as Irish or Danish Mild Cured bacon.

Even so, with all the drama offered by our quest, never forget the priority of each sunset. Knowing that we are but small parts of a very big whole. That our highest achievements will be measured in whom we loved and how content we were with whatever life offers us. My heart goes out to that young man and his parents! My heart goes out to him! Imagine his final moments – alone, in a foreign land! With these, my dear son, it is time for me to go. Know that, no matter what, my love for you and your sister is eternal. It will be my last thought when I die. The vision of you and my dear Minette! You guys are my entire world and as certain as I write these words today, one day you will read it and I will be gone. Know that my life was not just about bacon, but like Gabriel Dupetit, it is also about the art of living! Imitate me, my son! Live!!

Be well, my boy!  Take care of Lauren and Minette.

Lots of love from Denmark,

Your Dad.

Notes:

(1)  “St” is the abbreviation for “stone.”   Until as recent as the Second World War, the Smithfield market in London used the 8 lb to a stone measurement. (hansard.millbanksystems)

The stone weight differed according to the commodity weighed.  Animals were weighed in 14 lb to a stone before they were slaughtered and once slaughtered, the carcass and meat would be sold in 8 lb to a stone measure.  Spices were also sold in 8 lb to a stone weights.  (Newman, 1954)

(2)  A survey was done in the US in the 1950’s to determine the most common brine mix used for curing bacon at the time. (Dunker and Hankins, 1951: 6) Even though it is 60 years after this letter was presumably written, I include it since methods and formulations in those days seemed to have a longevity that easily would have remained all those years later.  The survey was also done among farmers, in an environment where innovation are notoriously slow.

(3)  How salty was this bacon in reality?  The recipe is used by most US farmers by the 1950’s was 10 lb (4.54kg) salt, 3 lb (1.36kg) of brown suger, 6 ounces (170g) of black pepper and 3 ounces (85g) of saltpeter.  10 pounds (4.54kg) of this mixture per 100 pounds (45.36kg) of meat.

The total weight of dry spices is therefore 6.07kg of which salt is 74% or  3.4kg.  This was applied at a ratio of 3.4kg salt per 45kg of meat or 1 kg salt per 13 kg of meat.  Not all salt was absorbed into the meat, but the meat was regularly re-salted over the curing period which means that this ratio would be applied many times over before curing was complete.  Compare this with the salt ratio targeted by us in 2016 of 25g per 1kg final product, this means that the bacon made with this recipe would be extremely salty, irrespective of the use of sugar to reduce the salty taste.  The bacon would have to be soaked in water first to draw out some of the excess salt, before consumed.

(4)  Eduard Polenske (1849-1911) was born in Ratzebuhr, Neustettin, Pommern, Germany on 27 Aug 1849 to Samuel G Polenski and Rosina Schultz. Eduard Reinhold Polenski married to Möller. He passed away in 1911 in Berlin, Germany. (Ancestry.  Polenske)

The Imperial Health Office was established on 16 July 1876 in Berlin,focussing on the medical and veterinary industry. At first it was a division of the Reich Chancellery and from 1879, fell under the Ministry of the Interior. In 1879, the “Law concerning the marketing of food, luxury foods and commodities” was adopted, and the Imperial Health Office was tasked with the responsible for monitoring compliance with it. Established in 1900, the Reichsgesundheitsrat supported the Imperial Health Office in its tasks. (Wikipedia. Kaiserliches Gesundheitsamt)

(5)  Brine is a solution of salt in water.

(6)  Qualitative and quantitative techniques for measuring nitrite and nitrates in food has been developed in the late 1800’s.  (Deacon, M;  Rice, T;  Summerhayes, C,  2001: 235, 236).  The earliest test for nitrites is probably the Griess test.  This is a chemical analysis test which detects the presence of organic nitrite compounds. The Griess reagent relies on a diazotization reaction which was first described in 1858 by Peter Griess.

Schaus and others puts the year of the discovery by Griess as 1879.  According to him,  Griess, a German Chemist used sulfanilic acid as a reagent together with α-naphthylamine in dilute sulfuric acid.  In his first publication Griess reported the occurrence of a positive nitrite reaction with human saliva, whereas negative reactions  were consistently obtained with freshly voided urine specimen from normal individuals.   (Schaus, R; M.D. 1956:  528)

(7)   Gayon and Dupetit’s discoveries include the following:

  • they demonstrated the “antagonistic effect of heat as well as oxygen on the process.”
  • “They also showed that individual organic compounds such as sugars, oils, and alcohols could supplant complex organic materials and serve as reductants for nitrate.”
  •  In 1886 they reported on “the isolation in pure culture of two strains of denitrifying bacteria.”

(Payne, W. J..  1986)

(8)  In reality, the key to understanding the function of the utalization of the oxygen atom is understanding cell respiration.  The purpose of cell respiration is the formation of ATP.  The organism needs nutrients for respiration which is obtained from sugar, amino acids, fatty acids and an oxidizing agent (electron acceptor), oxygen (codecogseqn-9).  Now, in environments where oxygen is depleted (where the rate of oxygen consumption is higher than oxygen supply, the bacteria respire nitrate.  The nitrate serves the purpose of the terminal electron acceptor, a function which is better performed by molecular oxygen, if it is available.  It is not only nitrite that is used by microorganisms in respiration when molecular oxygen is depleted.  Other electron acceptors are sulfate, iron and manganese oxides.

Introduction

The quest to understand how great bacon is made takes me around the world and through epic adventures. I tell the story by changing the setting from the 2000s to the late 1800s when much of the technology behind bacon curing was unraveled. I weave into the mix beautiful stories of Cape Town and use mostly my family as the other characters besides me and Oscar and Uncle Jeppe from Denmark, a good friend and someone to whom I owe much gratitude! A man who knows bacon! Most other characters have a real basis in history and I describe actual events and personal experiences set in a different historical context.

The cast I use to mold the story into is letters I wrote home during my travels.

The Danish Cooperatives

March 1891

My dear Minette,

It is Sunday afternoon.  I slept most of the morning.  I am excited and refreshed.  I know you are here in spirit.  I can sense you.  Life has turned out much more insanely exciting than I could ever have hoped for. The entire thing is a grand adventure of discovery.  I could never dream that trying to unlock the secrets of bacon would be as insanely exciting as it all turned out to be.  Hopefully, you will receive the letter I wrote yesterday before you get this one.  I will hold on to it and post it next Friday.

Getting Up

The morning was crisp and interesting.  Andreas’ dad is an impressive man.  He is very intelligent with an amazing knowledge of many things.  He gave me a lot of perspective on what Jeppe told me on Friday.  For example, how did it come about that a man of Jeppes age was exposed to learning new butchering and curing techniques?  Why was there in Denmark such a focus on continued education that people showed up for lessons by the Irish, in sufficient numbers to make a proper transfer of skills possible.

It often takes a prophet to change long help perceptions.  A visionary to change entrenched positions.  An inspirational man who draws his own strength from the Divine to lift peoples gaze from their own depressed positions and onto better things.  To instill hope.  These are however not all that is needed because these are often also the qualities of an imposter and someone who destroys.  What is needed are all these qualities with a simple and effective plan to improve things.  A person who can lead people to a better and more profitable future.

Andreas’ dad told me about just such a man.  In many ways, he is the father of the agricultural miracle of Denmark.  It may sound like a boring report on men and woman who lived very long ago, but the truth is that it is an inspirational story about men and woman with their backs against the wall.  Who triumphed against the odds.  The man at the center of the story is N. F. S. Grundtvig.  Denmark was an impoverished nation.  They lost Schleswig-Holstein to Germany.  The soil of their lands was depleted and yielding fewer crops with every harvest.  In all of Europe, the Danish soil seemed to be the poorest.   The conditions in 1864 were dire and farmers had little hope competing with Russia and America with their crops.  They were not making money.  Apart from little diversified agriculture, there was very little money in the country.  Farmers identified dairy farming as a lucrative diversification of their economy, but they lacked money to make their plans a reality.  The depleted soil on the farms offered little collateral for lenders to advance money against.

I wish so much that I would get every South African to hear their message.  We are a nation of faith and still, we complain as if we have no hope.  What we need in South Africa is a prophet, a visionary and a very good plan!  The plan will in all likelihood have to be built on very practical education!

Grundtvig was a churchman who lived between 1783 and 1872 and was described by some as the Apostle to Denmark.  He taught that Danish people must love their own country above all, more than any other real estate on earth.  He taught that Danes must love God and trust each other; their own skill and ability to solve problems; that success will come through cooperation.  The principal way to achieve this was through education and what he called the “cultivation of the people.”  This was distilled through his concept of high school which is completely different from high school in the rest of the world.

N. F. S. Grundtvig’s high schools were initially attended by people from the age of 18 to 60 or even older and everyone in between.  Every farmer’s adult son and daughter, every farmer himself or his wife, considered it a loss not to attend High School for at least one term.  The poor and the rich paid the same small fees and lectures covered an array of interesting subjects.  Religion and nationalism were part of the course, but it never dominated the other subjects.  Men and woman looked forward to high school in the same way as Americans looked forward to a trip to Europe.  What he achieved is that even more than the information that was imparted, a general method of teamwork was created which would become the basis for cooperative farming and production.  Later, men and women aged between 16 and 35 mostly attended these high schools.  Young men attended in the winter and young ladies, in the summer.  Experimental agricultural farms were set up around the schools.  The teaching was not done from textbooks, but from practice.

Cooperation

His teachings against individualism slowly but surely sowed the seeds which germinated into mutual trust and a belief that by doing things together, more can be achieved.  Directly as a result of this, in 1881/ 1882 the first cooperative dairy farm was established in Jutland.  The Danes realised that to be successful, they must find ways for their fields to yield better crops and they must develop better ways to use their crops.  Better than selling it at depressed margins on the open market in competition with the Russians and the Americans would be to utilise it to produce commodities.  On par with a relentless focus on scientific farming practices was unprecedented cooperation.  The middle man had to eliminate.  The farmer and the salesman joined forces and discovered that by cooperating they always had “something to go on,” a phrase which became an example of the new approach.

The cooperatives were set up where every member had equal rights.  Each member of the dairy cooperative had one vote and his milk was collected every morning and the cooperative agents returned the skimmed milk.  The cows, therefore, produced butter and feed for the pigs.  Money is loaned from the bank. Each member made himself responsible for repaying the lone in accordance with the number of cows he had.  Every seven days, the members received 25% of the value of the milk they delivered to the cooperative.  Apart from selling the milk to the cooperative, the member was entitled to his shares of the profit on the sale of the produce.  The cooperative kept 25% from which running expenses were paid and the loan was repaid.

There is another reason, Andreas’ dad tells me, why the Danish system works so well.  Not only did they manage themselves, but they also elected farmers to positions of power in government.  It was not only, like the Americans, for the people, by the people, but the Danes took it one step further.  The need and most pressing priority was their agriculture and so the cooperatives elected representatives for the farmers, by the farmers to the government.  These men and woman abhor profiteering so that the priority is the benefit of the many.  This hatred for large trusts and monopolies goes back to the old feudal system which was so prevalent in Europe.  Peasants did not own land, but in Denmark, this changed and the peasants were allowed to own their own farms.  This gave them every stimulus and motivation to improve the small farms.  It is said that 90% of all farmland in Denmark is owned by small scale farmers.  The first revolution in Danish agriculture was ownership.  This was only the beginning.

The new farm owners started protesting against rulership and land aristocracy.  They sought more political power and proper representation.  They worked out a constructive plan to break up the remaining large feudal farms and to distribute it among sons and daughters of the workers.  Farm ownership, a systematic and thorough education system and the cooperative model for farming and production all work together.  The one feeding the other and strengthening the overall agricultural experiment.  In large part, the middle man was eliminated and the few matters run by the state is done for the benefit of the farmers and not for the government to make a profit such as the railways.  Still, the Danish farmer is not a socialist.  They simply believe in cooperation who thinks in terms of self-help and are not reliant on the state for help.

As Andreas’ dad spoke, I again wished I could get him to South Africa to come and tell them how it was done in Denmark.  I know that cooperation runs much deeper than simply pooling resources.  The role of education and private ownership was the basis of the Danish miracle and I see no reason why the exact same model cant work in South Africa.  The one large reason I see is how deeply distrust runs between the different peoples who call South Africa their home.

Skimmed Milk to Pork to Bacon

In Denmark, it was probably the need to find a use for the skimmed milk that gave the farmers the idea of raising pigs in the same way that the need to feed cows indoor for nine months of the year forced them into intensive farming in fodder.   Pig farming therefore directly grew out of dairy farming.  It was going well with the establishment of cooperative pig farming and the live pigs were sold to Germany.

Before 1888, Danish farmers relied on selling all their pigs live to Germany.  The Germans, in turn, produced the finest Hamburg bacon and Hams from it and it was mainly sold to England.   A disaster struck the Danish pork industry when swine fever broke out in the country in the autumn of 1887.  This halted all export of live pigs.  Exports to Germany fell from 230 000 in 1886 to only 16 000 in 1888.  One of the most insane industrial transformations followed.  In a staggering display, the Danes identified the problem,  worked out the solution and dedicated every available nation resource to solving it.   The creation of large bacon curing cooperatives was born out of the need to switch from exporting live pigs to processed pork in the form of bacon and to sell it directly to the country where the Germans were selling the processed Danish pork namely England.  The project was a stunning success.  In 1887 the Danish bacon industry accounted for 230 000 live pigs and in 1895, converted from bacon production, 1 250 000 pigs.

The first step in bacon production is slaughtering.  On 14 July 1887, 500 farmers from the Horsens region created the first shared abattoir.  On 22 December 1887, the first co-operative abattoir in the world, Horsens Andelssvineslagteri (Horsen’s Share Abattoir), received their first live pigs for slaughter.  In 1887 and over the next few years eight such cooperative abattoirs were set up and there is still no end in sight where it will end.  Each is in excellent running condition.  As in the case with the dairy farmers, each member of the cooperative has only one vote.  The profit of the middleman and the volumes exported for butter and bacon is determined by the cooperative.  The market price is fixed in Copenhagen on a daily basis by an impartial committee.

Every farmer in Denmark or manager of a bacon curing plant cant be a scientific person, and yet, it is important that farmers and factory managers alike know something of the science underpinning their trade.  It is here where the high school lessons play an important role because it provides a solid foundation and the government is doing the rest.  They have a system of inspectors who look after farms and factories where they do the exact calculations, for example, to show how much butter must be produced from the milk of each cow.  The reason for the inspections was that the Danish Government were required to guarantee the quality of the bacon and the butter it delivered to England, but it had the double benefit of on the one hand guarantees the quality and satisfy the English requirements and on the other hand, improved the quality by assisting the farmers and producers.

The logic of cooperation was extended into England, the largest market for Danish bacon.  Some years ago the English bacon market was being serviced for the Danes by middlemen.  The farmers organised a selling agency in England to represent them known as the Danish Bacon Company of London.  Banking and buying in Denmark are also done cooperatively.  Every village has a cooperative store.

The farmer uses the state in another interesting way.  Commissions are sent abroad to study foreign methods.  It was most probably on one of these trips that the Danes came across the striking workers in Ireland whom they brought back to Denmark to teach them mild curing.  Mild curing technology that came from Ireland years earlier became the cornerstone of Danish bacon.  It was this industrialised model which allowed the Danes to become the undisputed leaders in the world bacon trade.

Neat, Prepared, Ready

Many years ago, on one of my visits to Johannesburg, I met another chemicals traders with the name of Willie Oosthuizen.  Willie told me that wherever I am in the world, before I leave home, every morning I must ask myself, “am I ready, prepared and neat?  These are according to him, the three essentials without which nobody will be in a position to use opportunities that come our way every day.

Thinking about the Danish Bacon trade, I realise that the government ensured that when the right time came, the industry was ready, prepared and in a general position of neatness.  It is a strange thing that as we walked through this small Danish town and I saw the small but neat Danish houses, that I could see this Danish approach to life in everything.  I do not see class differences between people.  I see people from all walks of life getting together in small coffee shops at the end of the day, celebrating life and sharing stories.

I can see how my quest to unravel good bacon curing is teaching me as much about life than it is teaching me about meat.  Andreas told me something this afternoon before I retired to my room which is very curious.  He told me that I am too quick to claim that this is the end of my quest.  That simply knowing the steps of bacon curing without understanding it is not to know the steps at all.  On the one hand, and on the other hand I think that this is not the end.  It is not even the beginning of the end.  My discovery thus far is quite possible only the end of the beginning.

Please give the kids all my love and to our dear parents.  Please give them both my letters to read before you sent it on to Oscar, James, and Will.  I will write Dawie Hyman, David de Villiers Graaff, and Uncle Jakobus separately.

I miss and love you dearly!
