Mapo tofu (麻婆豆腐) is a popular Chinese dish from Sichuan province. It consists of tofu set in a spicy sauce, typically a thin, oily, and bright red suspension, based on douban (fermented broad bean and chili paste) and douchi (fermented black beans), along with minced meat, traditionally beef. Variations exist with other ingredients such as water chestnuts, onions, other vegetables, or wood ear fungus. One account indicates that the dish existed as early as 1254, in a suburb of Chengdu, the capital city of Sichuan province.
