A juicy tomato story

Jeremy’s latest newsletter has a useful snippet on a paper on the history of the tomato in Europe. I’ll reproduce it below as a taster, but consider subscribing, as there’s lots of other interesting stuff too, on everything from pizza to chocolate.

Maybe you saw those beautiful illustrations of 16th century tomatoes that were doing the rounds a few days ago. They were prompted by a lovely paper from the Netherlands looking at the earliest tomatoes in Europe. The paper may be a bit heavy going, but the researchers published their own summary for the rest of us.

The paper sheds light on those first tomatoes to arrive, and in particular on the notion that these first fruits “were elongated, segmented, and gold in color. After all, that is how they were depicted, and they were called ‘pomo d’oro’: golden apple.” Herbarium specimens and old drawings, many of them newly digitised, revealed many different colours, shapes, and sizes, but not whether tomatoes originated in Peru or Mexico, the two leading candidates. The Dutch researchers sequenced the highly degraded DNA of their specimen and say that it was definitely not a wild plant, and shows strong similarities with three Mexican varieties and two from Peru.

The indigenous Andes population in Peru started domesticating a small wild cherry tomato. They brought this to Mexico, and there they developed the tomato with large fruit that we know today.

No herbarium specimen is ever likely to germinate, so to find out how these first tomatoes in Europe might have tasted the best bet, they suggest, is to go to Mexico and Peru. DNA analysis could probably indicate the closest known relatives for a taste test.

Now, will someone please examine critically the whole “tomatoes didn’t catch on because they were considered poisonous” thing, or is there already enough proof of that?
