1, the method of sufu is very simple. First of all, clean and cut into tofu blocks about 3 cm square and 6 mm thick, soak them in 2% salt water and steam them in a pot.

2. Steamed tofu blocks are fermented in a warm and dark place. The general temperature is 20℃ ~ 25℃. White or yellow fimbriae (called tofu embryos) can grow on the surface of tofu within 5 days, and then put them in a small pot. Sprinkle a layer of salt water on each layer of bean curd embryo (the ratio of salt water is 1: 2), cover and seal, and ferment again in 10 day to obtain fermented bean curd.
