What is the method of making freshly ground soy milk in a breakfast shop?

How to make freshly ground soy milk in breakfast shops:

1. Soak dry soybeans in advance, usually for more than 7 hours. According to the ratio of dry soybeans to glutinous rice 9:1, prepare the corresponding weight of glutinous rice, and the glutinous rice also needs to be soaked.

2. Place the soaked soybeans and glutinous rice in the soymilk machine, add water according to the ratio of 1:13, and the soymilk machine will start working again.

3. After the soy milk is poured out, filter it with a sieve to separate the bean dregs from the soy milk.

4. Pour the filtered soy milk into the pot, add an appropriate amount of sugar and cook.

5. Be sure to wait until the soy milk is 100% boiled before turning off the heat. Stir several times during this period to avoid the soy milk being mushy.
