What were the Amerindian contributions to the diets of Asian societies?
Corn is insanely popular in parts of Asia.
In Korea, one sight that confounds Westerners is the presence of corn on pizza. Throughout South Korea and China, steamed corn on the cob is popular fare from street vendors, and it's not even a variety that's popular in America.
Potatoes and sweet potatoes--also New World crops--are also staples of many Asian countries, and are also found on Korean pizza.
