Production method:

(1) Wash 5000 grams of glutinous rice with clear water, soak it for 1 hour, then pour it into a dustpan (a bamboo utensil used to wash rice and vegetables in the south, which looks like a dustpan in the north) and drain the water.

(2) Spread gauze on the steamer, pour the drained glutinous rice on it, steam it for 1 hour with strong fire, then pour it into the basin, and when the rice temperature is reduced to 20℃-40℃ with an electric fan (the origin of glutinous rice is different according to the types of distiller's yeast, even the temperature at different latitudes will be different), then pour a proper amount of cold boiled water into the basin and stir it evenly by hand. Grind the distiller's yeast into powder, put it in a basin and mix well again.

(3) Pour the evenly stirred glutinous rice into the jar, dig a small nest in the middle by hand, and then add a little cold boiled water to the remaining distiller's yeast powder and sprinkle it on the surface of the rice. Then cover the jar tightly with a wooden cover, wrap it with cotton wool, and put it in the grass nest. It will become mash in 3 days.
