Dougan

''Dougan'' () is a very firm variety of tofu () popular in Chinese cuisine. It differs from regular tofu in that it is firm whereas tofu is soft. It is made from soybeans with added calcium sulfate, and sometimes flavored with salt, soy sauce, and spices such as cinnamon, star anise, and licorice.

This food's name is composed of two syllables, dòu (豆, "bean"), and gān (). This is different from tofu (which also has two syllables), but the second syllable in tofu is "fu" (腐). The full name is called ''doufu gan'' ().

It is important to distinguish between tofu and ''dougan'', as it may not be appropriate to substitute tofu for ''dougan'' in recipes which call for ''dougan''.

''Dougan'' has a lower moisture content than tofu in that it is drier, and also by weight, where ''dougan'' has a greater bean-to-water ratio than tofu. This means that ''dougan'' contains more protein per gram, as the proportion of water is less.

''Dougan'' is different from firm tofu by being even firmer. It is also different from seitan, which is made from wheat instead of soy. Provided by Wikipedia
