1, boil the soybeans, cook them overnight, and dry them (the water must be boiled dry, so as not to paste the pot), and the soybeans turn brown (a beautiful color). Egoism grasps the temperature.

2. Grind with a blender. When it is dry, make it into the shape of two bricks on the chopping board or table by hand. As close to the dock as possible. It needs to be hot.

When it gets cold, wrap it in paper (they used to use newspapers, but now you can do whatever you want). The old man has a saying that it is best to be around the second day of the second lunar month. Put it in a place with temperature and humidity, about 23 degrees, not too dry (the purpose is to let it ferment). On the eighth day of the fourth lunar month, 18, 28.

4, open, there are capsules (a mold) inside and outside. Break it into small pieces and dry it (don't dry it, put it in a place with good air circulation for about 3 or 4 days). Saline water: beans = 3: 1. Then boil water to melt salt, add dried beans and add water to 3 or 4 times. Then put it in the sun and tie your container of beans with a piece of cloth (to prevent dust, mosquitoes and flies).

5. Untie the cloth and stir it every day, three times in the morning and three times in the evening, each time 10 minute. There will be foam on the surface. Take them out with a spoon. Repeat for about a month and you can eat it.
