Dougan

Dougan is a firm variety of tofu (Chinese: 豆腐; pinyin: dòufu) which is 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 (simplified Chinese: 干; traditional Chinese: 乾; lit. 'dry'). 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 (simplified Chinese: 豆腐干; traditional Chinese: 豆腐乾; lit. 'dried tofu'). 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.
