Every cuisine except for those of uncontacted tribes is shaped by migration, trade, economics, etc. The ingredients Italian cuisine is most known for are pasta (derived from early Arabic forms of noodles) and tomatoes (South America.) You can say Lasagna was invented in Italy, but you can’t say it’s the product of cultural purity that Europeans tend to think of their cuisines as.
Only to the degree that the hamburger actually is an original American dish does “pure” cuisine exist. People looking to discredit American food call it German, and while it evolved from Hamburg steak, by most accounts the first people to turn that into a sandwich, and then top it with cheese, lettuce, and tomato instead of gravy were in the United States. Burgers are German only to the degree that Bahn Mi is French.
We do but it’s about more plants and animals than humans.
