Ingredients and Preparation

Hairy tofu, also known as stinky tofu, is a Chinese fermented tofu dish. It is made with high-quality soybeans, which are first subjected to traditional processes such as sifting, cleaning, soaking, refining, filtering, and pressing. The soybeans are then transformed into bean curd through a process involving the use of coagulants, like magnesium chloride or calcium sulfate, mixed with water.

White Mold and Hair-Like Filaments

The highlight of hairy tofu production is the development of a white mold on the tofu’s surface. Rhizopus, a type of fungal spore, is responsible for this characteristic appearance.
