2. Pour the soybeans you want to make into a big barrel and soak them in water.
3. Wait two hours to see that the surface of the beans is bright, the whole beans are bulging and the water is almost gone. Just add water and keep soaking for two hours.
4. At this time, the soybeans have drunk enough water, and the water leaks out through the filter screen, adding a small amount of water, and grinding the beans into soybean milk with a juicer.
5. Sieve the beaten soybean milk with water and gauze, and dump the remaining bean dregs.
6. Pour the screened soybean milk into the pot and bring it to a boil over high fire to remove bubbles on the surface.
7. At this time, there is a thin skin on the surface of the soybean milk in the pot, which is the so-called bean skin. Lift this bean skin from the middle with a long bamboo stick. Put it in the sun to dry. It's done.
