2. soak beans. Grab two handfuls of mung beans (1 ~ 1 two halves), wash and soak 10 ~ 24 hours. If you think it's a little long and you're afraid you don't have time to take care of her, you can soak it in warm water. Because the skin of this kind of mung bean is hard, the teeth are not easy to grow out. After soaking in water, teeth grow out more easily.

3. After soaking for 12 hours, the bean shell cracked, indicating that it has been successful.

4. Prepare steamer, towel and black cotton cloth (old clothes). Because there is a hole under the steamer, the air can get in better, then the towel absorbs water, and then the bean sprouts are placed on it to provide moisture for the beans. The black cotton cloth is used to shade the light.

5. spread a wet towel in the pot. This towel must be wet first, but not the kind with plenty of water.

6. Spread the soaked mung beans evenly.

7. Cover with wet black cotton cloth to make long bean sprouts slender (slim). The black cotton cloth in here must be opaque. If it is transparent, it will change color and will not grow into a thin and long bean sprout shape.

8. On the fourth day, bean sprouts will do.
