Production steps:

1. Soak soybeans in clear water 12 hours or more.

2. The soaked soybean is about twice as big as the original one.

3. Drain and put it in a steamer (to avoid leakage, put corn leaves), then sprinkle with white sugar and put it in a pressure cooker for about 40 minutes (as long as it can be dispersed immediately by hand)?

4. Pour the soybeans into the natto screen, cool to about 30 degrees, and pour 4 grams of natto powder.

5. Mix well with sterilized chopsticks.

6. Put it into the yogurt machine to select natto function, and the whole process takes about 16 hours.
