Potatoes are (almost) perfect

potato

The USDA’s Food and Nutrition Service runs a program for Women, Infants and Children that subsidises specific foods for eligible women and their children. Back when it started, the WIC program excluded potatoes, on the grounds that “Americans already eat enough potatoes”. Potato growers – and their representatives – don’t like that. For one, they think it sends the wrong message about the nutritional value of potatoes. And so, in 2010, the Executive Director of the Washington State Potato Commission, Chris Voigt, launched a protest. He decided to eat nothing but potatoes for 60 days, gaining massive amounts of publicity but not – yet – a change in the WIC list of approved foods. ((Mr Voigt says that “Potatoes are still excluded from the WIC program, unless you buy them at a Farmers Market.”.)) However, while the world marvelled at Voigt’s dedication to the people who pay his salary, one grower in neighbouring Oregon said “Hey, what’s so hard about that? Last winter, I ate pretty nearly all potatoes for about six months. It was a feast all winter!”

Carol Deppe – author of Breed Your Own Vegetable Varieties and The Resilient Gardener – ate almost nothing but potatoes because that’s what she had, and because she really understands the nutritional value of potatoes. She points out that potatoes contain more than 2% protein, which doesn’t sound like much when you compare it to the 9% in rice or the 12% and more in wheat. But those are dry-weight values. On that basis, potato comes in at better than 10% protein, and that protein is both more balanced and better absorbed that wheat protein. This isn’t exactly news. It’s been known since the late 19th century that if you’re getting all your calories from potatoes, then you’re probably getting all the protein you need too. But that knowledge seems to have been forgotten, and Deppe thinks she knows why:

When the USDA denies WIC-program women, infants, and children their potatoes, in spite of the potato’s known excellence as a food, in spite of how much we all like it, I think I detect a subtly Euro-centric as well as classist message: “The right way to eat is like upper-class Europeans, not like New Worlders or peasants.” The problem is bigger than failing to recognize that Americans are not all Europeans, that even most European-Americans now embrace food traditions from many lands and cultures, and that most of us are closer to being peasants than to being medieval European royalty. To reject the potato is to be several hundred years out of date. Rejecting the potato represents a failure to learn some of the most important climate-change lessons of the Little Ice Age. I think the USDA should revisit its potato policy.

So do lots of other people, including potato growers, and although potatoes are again up for consideration, it isn’t clear whether this time they will make it onto the hallowed WIC list. In the meantime, they remain an excellent and nutritious food.

Notes

  1. The Effect of Food Restriction During War on Mortality in Copenhagen is Dr Mikkel Hindhede’s account, in the Journal of the American Medical Association, of the impact of the World War I blockade on deaths in Denmark. By encouraging Danes to switch to a more vegetarian diet, Hindhede effectively saved 6300 lives. Mortality was actually lower during the blockade than before or after. By contrast Germany, also affected by the blockade, saw widespread famine.
  2. There’s an online account of Chris Voigt’s 60-day 20-a-day potato marathon. It’s pretty broken.
  3. I hope to have more from Carol Deppe in a future podcast.

Neanderthal Diets Grateful that they didn't brush their teeth

Mandible small

Neanderthals did not descale their teeth regularly, for which modern scientists can be very thankful. Embedded in the fossilized calculus, or tartar, on teeth from the Shanidar cave, in Iraqi Kurdistan, and elsewhere are some remarkable remains that are beginning to shed far more light on what Neanderthals ate. I don’t want to give too much away just yet. Let’s just say that if, like me, when you think of the Neanderthal diet you think of a bunch of cavemen and women sitting around chewing their way through a woolly mammoth, you’re in for a surprise.

My guide through the recent discoveries on Neanderthal diet is John Speth, Emeritus Professor of Anthropology at the University of Michigan.

Amanda Henry’s research clearly points to moist-cooked starch grains in the mouths of Neanderthals (but did they swallow?). Archaeologists, however, have found almost no evidence of Neanderthals using the hot-rocks boil-in-a-bag method of modern people who lack fire-proof containers. And surprisingly, they didn’t know what John Speth discovered while watching TV in a motel room: that it is perfectly possible to boil water in a flimsy container over a direct fire. In the interests of time I had to cut his fascinating description of an experiment to make maple syrup by boiling the sap in a birch-bark tray over an open fire, which concluded that it was “both efficient and worthwhile”. So, now that they know it can be done, how long before they discover it was done?

There is evidence that Neanderthals ate moist-cooked starch. There is evidence that one can moist-cook without fire-proof containers and hot rocks. All we need now is evidence that Neanderthals used similar techniques, and the palaeo-dieters can add a nice mess of potage to their daily fare.

OZ97a — a great British hop

Hop flower Perhaps you saw an article in a recent BBC News magazine about how US craft beer is inspiring British brewers. The Americans say they’re not bound by tradition, with the clear implication that the Brits are. And yet it was insipid American beers — like making love in a canoe, we used to say — that triggered the rise of microbreweries and craft beers. Now very hoppy beers with all kinds of flavours are big there, and increasingly big in the UK, and one result has been a resurgence of interest in British-bred hops. One of these, OZ97a, is being hailed as a new star of British brewing, not least by Mark Dredge, an award-winning beer writer. I read about OZ97a at Pencil and Spoon, Mark’s blog. Of course I had to talk to him.

The thing about OZ97a is that it isn’t a new variety. It was bred in the late 1940s or early 1950s, but when brewers first got a whiff of it, in 1960, they rejected it out of hand. Way too tasty, with all that fruitiness. Not what beer-drinkers want. But with the rise of intensely flavourful US beers, by 2012 OZ97a was ripe for a renaissance, and a couple of test batches confirmed it as a great hop. So how had it survived? In a field genebank, run by the British Hop Association.

It is quite common to hear that genebanks should be maintained as a source of breeding material to adapt to changing conditions. But this is the first time I’ve heard of the changing tastes of consumers being the conditions that need adapting to.

Do good chocolate

PiuraThe world of fine chocolate has seen some major change in the past few years, much of it focused on the rise of so-called “bean to bar” chocolate made by smallish producers with an eye on the distinctive qualities of different cacao beans. One company that’s been making a name for itself is Original Beans, which markets a package that tells “The story of cacao in four bars” that recently won a silver medal for packaging at the Academy of Chocolate awards in London. Last summer, I was lucky enough to sit down with Sudi Pigott, a consultant to Original Beans, and taste a couple of them.

I came away from the interview with half a bar of one we didn’t taste, the Piura Porcelana. Typing the ID code into the Original Beans website took me lickety split to a page all about that chocolate. It’s an intriguing story, the Porcelana variety being characterised by beans that are a lot lighter in colour than most cacao. Porcelana, of which there are said to be 33 genetically different types, was apparently rediscovered by Original Beans in 2007, since when the company has been working with local farmers and NGOs to boost production. But there are some niggles too. It’s strange, for example, to be told:

The Piura Porcelana’s origin is located on the foothills of a mountain range reaching above 2000 meters, called the Sierra Piura. The area is part of the xxx biodiversity hotspot, with bears etc. . Much of the original forest has been cut down over the past decades, resulting in changing weather and water supply. Now it is being replanted and restored.

xxx biodiversity hotspot? Bears etc? Is somebody still doing fact-checking and research for the copy?

Original Beans is good chocolate, no doubt about that, although there’s also been a bit of a to-do in the rarefied world of chocosnobs about who exactly makes Original Beans’ chocolate. The packaging says Made in Switzerland, although the company is headquartered in Amsterdam. CEO and founder Phillip Kauffmann is quite open about it being made by Felchlin, at least when asked, but that information is not widely available. Is that a problem? Not to me. There are people who make chocolate, and people who make things from chocolate, and they’re often not the same people. Apparently at the fine end of the “beans to bar” world that matters. Original Beans does everything except make the bars; I think that’s acceptable.

Is the price equally acceptable? I don’t know; what should good chocolate cost? Fair prices for farmers, men and women alike, no child labour, environmental sustainability, conservation, all that … what’s it worth?

I’m not the first to ask the question What Is The True Cost of Chocolate? of Original Beans, and the answers given then, in 2009, certainly have a lot of feelgood about them. In truth, though, I don’t think we’re any nearer an answer, and we won’t be until we have independent audits and much more transparency than most businesses could survive. There’s a real dilemma here. Original Beans and many other topnotch chocolate makers can charge what they do in large part because they are making smaller batches. They’re competing with one another, not with the industrial giants. Industrial chocolate really is a rather ghastly business in all sorts of ways, and yet I don’t see the vast majority of its customers switching to more ethical products, and if they did, I don’t see the ethics surviving the onslaught.

Notes

  1. Original Beans’ local partner in Peru made a video about Piura Porcelana.
  2. Here’s another video, of Original Beans’ Phillip Kauffmann talking about Cru Virunga.
  3. Most of the world’s chocolate is now grown in Africa, away from the pests and diseases of its home in Latin America. Here’s a long article about its first home in Africa, São Tomé and Príncipe.
  4. Oxfam has been running a campaign to persuade industrial chocolate to do better; it may be starting to bite.

Air-cured sausages

AssortedAmong the more miraculous edible transformations is the one that turns raw meat, salt and a few basic spices into some of the most delicious foods around.

Time was when curing meat, especially stuffed into a casing to make a sausage, was the only way both to use every part of an animal and to help make it last longer than raw meat. Done right, a sausage would stay good to the next slaughtering season and beyond.

The process relied on the skill of the sausage-maker, the help of beneficial bacteria and moulds, the right conditions, a great deal of patience, and sometimes luck. Luck is less of a factor now, because to keep up with demand the vast majority of cured meats are produced in artificial conditions of controlled precision. Here and there, though, the old ways survive. Jan Davison spent months touring the sausage high-spots of Europe looking for the genuine article, and shared some of her favourites at the Oxford Symposium on Food and Cooking last year.

The Sausages

Salchichon

Mortadella di Camaiore, from the Triglia family in Camaiore, Italy.

Corallina di Norcia, from I Fratelli Ansuini (The Pig Brothers? Surely not.) in Norcia, Italy.

Finocchiona di Suino Grigio, from Sergio Falaschi in San Miniato, Italy. I think the Suino Grigio is a cross between the Large White and the fabled Cinta Senese, which almost did for the latter.

Salchichón de Vic from Casa Riera Ordeix, in Vic, Spain.

The chorizo Jan mentioned in the interview we did not taste. She sent her notes:

Lomo iberico bellota – Señorio de Montana, Spain. Along with ham, lomo, cured loin of pork is the highest expression of the curer’s art; especially when it is made from Spain’s indigenous black pig, the Iberico, fattened on bellota – acorns. The loin, left as a single roll of meat almost a metre in length,  is seasoned almost imperceptibly with pimentón, (a spicy type of paprika), sea salt, fresh garlic and oregano, before being stuffed into a gut and left to cure slowly over several months. Lomo Ibérico bellota is a cured sausage is to be savoured … slowly; the lomo melts in the mouth releasing complex, nutty flavours.

Ahle Wurscht, from Thomas Koch in Calden, Germany. There’s a video of Ahle Wurscht being made, which I had subtitled, but WordPress does not yet permit embedding videos from Universal Subtitles, so you’ll have to just click the link. That video is not from Thomas Koch, although he does have some videos on his site.

Notes

  1. Jan Davison is writing a book on English Sausages for The English Kitchen series at Prospect Books. All being well it will be published in 2014.
  2. Food safety agencies have been very wary about meat cured in restaurants and at home, sometimes with justification. But there really is nothing to be scared of if you take reasonable precautions. A great place to start is at Michael Ruhlman’s blog, and one of his excellent books. I haven’t done so myself, but everyone says Ruhlman is the boss.
