Stinky tofu (Chinese: 臭豆腐; pinyin: chòu dòufu) is a Chinese form of fermented tofu that has a strong odor. It is usually sold at night markets or roadside stands as a snack, or in lunch bars as a side dish, rather than in restaurants. Traditionally the dish is fermented in a brine with vegetables and meat, sometimes for months. Modern factory-produced stinky tofu is marinated in brine for one or two days to add odor. Generally speaking, stinky tofu is mainly made of tofu. After fermentation of edible mold, tofu can produce a large number of B vitamins, a variety of minerals and trace elements. The flavor of stinky tofu is bitter.
