2. Use a soymilk machine to break the soybeans, 50 grams of soybeans corresponds to 500 grams of water, and then filter out the bean dregs (if it is a fully automatic soymilk machine, add the soybeans and wait until the soymilk is cooked).

3. Cook soybean milk in the pot. When there is floating foam in the pot, it needs to be filtered out with a strainer. Wait for the soybean milk to boil for 4 minutes, and then add sugar.

4. When everyone cooks soybean milk, bring it to a boil with high fire and stew it for 3-4 minutes with low fire, which can make the soybean milk taste mellow.

5. After the soybean milk is boiled, it must be boiled for 3-4 minutes, so that the toxins in the soybean milk can be completely removed. Don't be lazy. This step is the most critical.
