This gate keeping of cuisine is ridiculous. It would logically follow that you have to throw out anything that’s made with something originally from a different zone. So no potatoes, tomatoes, corn or other new world crops… Well, anywhere but one of these sections. Anything that comes from cultural exchange is, apparently, right out. So good luck with whatever the fuck they were eating in mesopotamia and the India river valley civilisation. I hope you like your beer to be bread.
