1. First, wash an appropriate amount of dry broad beans, add an appropriate amount of water, preferably just enough to cover the beans, and soak them overnight.

2. Pour out the water after the tofu skin is soaked until soft, change the water several times in between, and then drain the water. Cover the beans with gauze and place them in a place with an appropriate temperature.

3. Change the water once a day. After changing the water, it is best to shake the pot a few times and let the beans turn over in the pot. This way the temperature and humidity will be uniform, and the broad beans will sprout in 3-4 days.

4. Broad beans, also known as southern beans, peas, etc., belong to the Fabaceae and pea genus, and are annual or perennial herbaceous plants. Broad beans are the third most important winter edible bean crop in the world. Broad beans have high nutritional value and their protein content is 25-35. Broad beans are also rich in sugar, minerals, vitamins, calcium and iron. In addition, as a nitrogen-fixing crop, broad beans can convert molecular nitrogen in nature into nitrogen compounds and increase soil nitrogen content.
