Korean cuisine emphasizes vegetables, meats cooked simply without oil, and fermented foods. Rice forms the backbone of meals along with varied banchan (small side dishes) and seafood. Representative dishes include bibimbap (mixed rice with vegetables and meat), tteok (rice cakes), and kimchi (fermented spicy cabbage), which are integral to meals. Fermentation, which can take months, is a key process that improves the taste and nutrition of traditional foods like soybean paste, soy sauce, chili paste, and fish sauce. Grilled meats like bulgogi (marinated beef) and kalbi (beef ribs) are also popular components of Korean meals.
