What is a food that is a good example of cultural diffusion, that is fairly early to research?
If it’s a style of food that you need, many cultures share the idea of a dish that has a filling rolled up and wrapped inside some type of dough: Chinese egg rolls, Russian blinis, Eastern European (Jewish) blintzes, Mexican burritos, Italian baked ziti and cannoli…If you mean a particular dish that traveled from one culture to another, noodles were originally from China and eventually were introduced to Italy (it’s said that Marco Polo brought them, but I don’t know if that’s a proven fact). If you mean a dish that’s common to many different cultures, then I’m sure that chicken soup would win!
