Hey, guess what, the foreign names for Jerusalem artichoke are also wrong, in a different way, people used to be terrible at naming food! I totally included this in my mail, but it didn't make the cut:
"Did you think the name in other languages is somehow a correct one? Well, the answer is no again, as it's called topinambour in a bunch of languages for an equally incorrect reason. It's named after the name for some peoples from the coastal area of Brazil where they thought it came from, which is Tupinambā. It's actually from the east coast of North America"
