Red bean, also called red bean, is an annual erect or twining herb. Plants can be 30 to 90 cm high, and the plants are sparse and hairy. Red beans like temperature, light and waterlogging. The whole growth period should be above 10 degrees Celsius, and the effective accumulated temperature should be 20 to 25 degrees Celsius. Generally speaking, they begin to germinate and emerge at 8 to 65,438+02 degrees Celsius. Red beans are sensitive to light, and premature sowing prolongs the growth period.

Method for cooking red beans:

1. First, select red beans with full particles and bright colors, and eliminate bad red beans with wormholes and impurity particles;

2. Put the cleaned red beans into a bowl and soak them in water for one night;

3. Take out the soaked red beans the next day and put them in the refrigerator for 2 hours before taking them out;

4. Then put the red beans in the bowl into a boiling pot and add a little water. The water can cover the red beans and then burn them until the water boils;

5. After the water is boiled, simmer for about 10 minute, lift the lid, take it out and put it in a bowl. At this time, the beans have swelled a lot compared with those when they are uncooked, and they can be eaten when they are cooled.
