Characteristics
Fermented bean curd has a special mouthfeel similar to certain dairy products due to the breakdown of its proteins which takes place during the air drying and fermentation. Lacking strong flavor, fermented bean curd takes on the aroma and taste of its soaking liquid. The flavor is salty with mild sweetness. The texture and taste of fermented bean curd resembles a firm, smooth paste not unlike creamy blue cheese. (Indeed, this kind of tofu is sometimes called "Chinese cheese" in English). Refrigerated, it can be kept for several years, during which time its flavor is believed to improve.
