The ancestor of tofu pudding is history.

Bean curd, also known as tofu, is a famous snack of Han nationality, which is divided into sweet and salty. Generally speaking, sweets are mainly distributed in the south of China (sweet bean curd flower), while the latter is in the north of China (salty bean curd brain). Tofu pudding is made by soaking soybeans for about 4 to 8 hours according to varieties or personal preferences. Soybeans are soaked in water, beaten, filtered, boiled and then cooled to 90℃.

The delicious skill of tofu pudding lies in the temperature control of the fusion of soybean milk and coagulant, as well as the speed and skill of making tofu pudding.
