Scouser from lobscouse, Kraut from sauerkraut, frogs… What are other demonyms derived from food?

In Dutch kaaskop (=cheese head) refers to Dutch people, especially from the North and South Holland provinces. In French rosbif is a slightly mocking reference to the English.

I'm curious about any words derived from food referring to people in states, regions, cities, etc.
