History
Gimbap (literally seaweed rice) developed in the Japanese colonial period (1910-1945), with visible influence from Japanese maki sushi in the rolling technique. However, Korean gimbap diverged significantly: the rice is dressed with sesame oil (not vinegar), the fillings are cooked (not raw), and the dish is eaten as a portable lunch or snack rather than a restaurant meal. Mayak gimbap, tiny thin rolls served at Gwangjang Market, are made with minimal filling and served with a mustard and soy dipping sauce. The word mayak (narcotic) refers to how addictively compelling the simple roll is, not to any actual ingredient.
