beancurd

Beancurd, also known as tofu (from the Japanese tōfu, derived from Chinese dòufu), is a curd product made from soy milk, the liquid extracted from soaked and ground soybeans. The production process involves coagulating soy milk using nigari (magnesium chloride), gypsum (calcium sulfate), or other coagulants—similar to cheese-making from dairy milk. The resulting curds are then pressed into blocks of varying firmness. Beancurd originated in China during the Han Dynasty and later became central to East Asian cuisines. It is white to pale yellow in color with a mild, subtle bean flavor and a smooth, custard-like texture that varies significantly by firmness level.

The ingredient encompasses multiple varieties across a spectrum of textures: silken (soft and delicate), firm (denser, holds shape better), and extra-firm (suitable for cooking methods requiring structural integrity). Some specialty forms include pressed/tofu skin (yúbǐ), and fermented varieties such as furu or chòujiàng.

Beancurd functions as a versatile protein base in East Asian cuisines, particularly Chinese, Japanese, Korean, and Vietnamese cooking. It is prepared through diverse methods: braised in soy-based sauces, stir-fried, deep-fried until crispy, added to soups and broths, or served chilled with simple dressings. In Japanese cuisine, it appears as agedashi tofu or miso soup components; in Chinese cuisine, dishes like ma la tofu and tofu skin rolls are canonical. Beancurd readily absorbs flavors from accompanying seasonings and marinades, making it valuable for both savory and, occasionally, slightly sweet preparations. Its neutral taste and adaptable texture allow integration into both traditional and contemporary fusion cooking.
