Korean cuisine has evolved through centuries of social and political change. Originating from ancient agricultural and nomadic traditions in the Korean peninsula and southern Manchuria, Korean cuisine has evolved through a complex interaction of the natural environment and different cultural trends.
Korean cuisine is largely based on rice, vegetables, and meats. Traditional Korean meals are noted for the number of side dishes (반찬; banchan) that accompany steam-cooked short-grain rice. Kimchi is almost always served at every meal. Commonly used ingredients include sesame oil, doenjang (fermented bean paste), soy sauce, salt, garlic, ginger, pepper flakes, gochujang (fermented red chili paste) and cabbage.
Ingredients and dishes vary by province. Many regional dishes have become national, and dishes that were once regional have proliferated in different variations across the country. Korean royal court cuisine once brought all of the unique regional specialties together for the royal family. Foods are regulated by Korean cultural etiquette.
Grains have been one of the most important staples of the Korean diet. Early myths of the foundations of various kingdoms in Korea center on grains. One foundation myth relates to Jumong, who received barley seeds from two doves sent by his mother after establishing the kingdom of Goguryeo. Yet another myth speaks of the three founding deities of Jeju Island, who were to be wed to the three princesses of Tamna; the deities brought seeds of five grains which were the first seeds planted, which in turn became the first instance of farming.
