The most recent extension of the containment zone now covers the whole of the Salento peninsulaIn 2013, a few olive trees near Gallipoli, in Lecce province in the heel of Italy’s boot, seemed to be dying of drought even though there was water. Turned out they had a disease caused by a nasty bacterium, Xylella fastidiosa, and it was the first time this particular disease had been identified in Europe. In California, where Xylella causes Pierce’s Disease in grapevines, it costs about a million dollars a year to try and control it. Plans were quickly drawn up in an attempt to control the disease, and equally quickly disrupted.

One of the 10 potentially resistant olive seedlings discovered in a dead olive grove Instead of killing maybe 3000 trees, more than four million have died in the past six years, and the disease is completely out of hand. When I was in Puglia in 2015, having just got interested in the story, it was quite exciting to see the occasional dead tree, marked for removal. This year, I was sickened to find whole landscapes, once covered with the glittering silver of olive leaves, brown and lifeless.

How did that happen?


Notes


* Many, many sources provided the information that underpins this episode, notably Diffusion of xylella in Italian olive trees, a website that acts as a kind of clearing house, and the pages it linked to.
* An earlier episode on Xylella clearly wasn’t pessimistic enough.
* Music by Dasgoat and PSOVOD on Freesound and Podington Bear.
* Photos by me, except for the seedling, which I found here.

The last supper was a Passover Seder, and for two thousand years Passover and Easter have been linked. The links, however, are complex, which is why I am taking the opportunity to expand on a five-year-old episode.

The rituals of the Passover dinner have been in place for thousands of years, although always open to interpretation and evolution. And yet, although different Christian traditions have their ritual Easter foods, there don’t seem to be any universals. The episode looks at these two contrasting aspects of ritual foods.

First, I talked to Susan Weingarten talks about the Seder dinner and especially an item essential on the Passover table that is not mentioned in God’s original instructions for the last supper of the Israelites in Egypt. While nobody knows how it came to be, every Jewish culture has its own version of haroset and its own idea of what it means.

Edna Holmgren and her daughter Lois Long at the Hall of Fame celebration in 1988Then, I spoke to Lois Long about a recipe made famous by her mother, Edna M. Holmgren. Magic Marshmallow Crescent Puffs won the Pillsbury Bake-Off in 1969. Later, they were expropriated by some Christians to retell the story of the resurrection, though personally I doubt they will ever become universal.

The Recipe



This copy of Edna Holmgren’s recipe is not quite the original. Lois Long told me that “the flour in the cinnamon sugar mixture was Pillsbury’s idea. I cut it down to 1 tbsp but I don’t like it. The original recipe has no flour.” I do wonder what it is there for. Possibly to soak up melting gooeyness, because many of the comments on the Hall of Fame website are complaints about the mess if the pastry isn’t very carefully sealed.

Notes


* Susan Weingarten’s book Haroset: A Taste of Jewish History is published by The Toby Press.
* Huge thanks to Lois Long for sharing her time, her memories, and copies of some of her memorabilia.
* The cover image is of an illuminated manuscript from the workshop of Valentine Noh in Prague, about 1470. The Passover plate is Italian majolica from The Magnes Collection of Jewish Art and Life at the University of California, Berkeley.

Passover and Easter Revisited





Malta, just off the coast of Sicily in the middle of the Mediterranean, has always been of enormous strategic importance. As a result it has been claimed, and fought over, by empire after empire. Each time it was vulnerable to a blockade of essential food supplies because the tiny island — Malta is only 27 kilometres long — cannot possibly feed itself. Despite this history, going into World War II neither the British colonial government nor the Maltese people were prepared for the inevitable blockade. When rationing was imposed, however, the authorities deliberately turned a blind eye to those who were finding ways to evade the restrictions of the black market. It made sense to do so, as I heard from Maltese historian Noel Buttigieg.

Malta Besieged & Black-market Intrigues





Spina bifida is a neural tube defect that is one of the most common severe birth defects in the world. The main cause is a lack of folate vitamin in the diet, and in 1991, the UK’s Medical Research Council halted a trial of folic acid supplementation early because it was obvious that the supplement was preventing a large number of cases. At the time, the trial’s authors concluded: “public health measures should be taken to ensure that the diet of all women who may bear children contains an adequate amount of folic acid.”

The United States was relatively quick to act, mandating flour be fortified with folic acid in 1998, followed by around 80 countries worldwide. Countries with mandatory fortification have seen a drop in neural tube defects of between one third and one half. But not the European Union nor, until recently, the United Kingdom.

The European Union concedes: “There has been no real progress in preventing NTDs in Europe since folic acid supplementation was shown to be an effective preventive measure.”

Finally, the UK has put forward proposals to fortify white flour, but many doctors say they could do much more. Europe is still to act.

Notes


* The US Centers for Disease Control has an excellent series of pages on neural tube defects with links to a lot more research.
* The European Union also has a page on Folic Acid and Neural Tube Defects.

The Case for Folic Acid Fortification





Anthony MongielloA recent documentary tells the story of how a kid from Brooklyn invented the stuffed crust pizza, sued Pizza Hut for ripping him off, and lost. It is a fascinating story, and left me in no doubt about who actually invented the stuffed crust pizza: Anthony Mongiello, that kid from Brooklyn. But it was the incidental asides Anthony dropped in the documentary, along with a look at Formaggio Cheese, the company he built, that really made me want to talk to him about his family of cheese engineers and his own history as a cheese inventor.

Notes


* Take a look at Formaggio Cheese if you want to get a better idea of the “75 different Fresh Mozzarella products” they offer.
* Stolen Dough, the documentary, is available on a few streaming channels.
* There’s a report of the case that I certainly am not competent to judge on its merits. Still, even if Pizza Hut did not infringe on Anthony Mongiello’s legal rights, the company’s moral judgement leaves a lot to be desired.
* Would you like to see Italian mozarella di bufala DOP being made? Of course you would.

Anthony Mongiello, Inventor of the Stuffed Crust Pizza





Harry RobsonSix thousand years ago in northern Europe, the first Neolithic farmers were bumping up against Mesolithic people, who made a living hunting and fishing and gathering wild plants. Both groups of people made ceramic cooking vessels for their food, and those pots have now revealed that in many respects the diets of the two cultures were more alike than different. The hunter-gatherers were processing dairy foods, while the farmers were cooking fish and other aquatic resources. That’s the conclusion of a massive study of more than 1000 pot fragments by 30 scientists. Harry Robson, one of the team leaders, explained the results and the light they shed onto the transition to farming.
