Choudoufu

Stinky tofu 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. Unlike cheese, stinky tofu fermentation does not have a fixed formula for starter bacteria; wide regional and individual variations exist in manufacturing and preparation.
