The red beans used to make rice dumplings need to be soaked for half an hour.

If you have enough time, you can soak it one night in advance. First, wash the red beans and soak them in cold or warm water for one night. When the weather is hot, you can put them in the refrigerator for soaking. (The purpose of soaking overnight is to allow the beans to fully rise, so that they can be easily cooked when cooked the next day). It should be noted that the water for soaking red beans should not be soaked in hot water, because soaking in hot water will cause the loss of nutrients in the red beans. It is recommended to use cold water or cool boiled water.

Preservation of red beans:

In order to keep red beans fresh and prevent them from deterioration or tooth decay, it is best to store red beans in a dry place. You can store red beans in a sealed jar. The red beans stored in this way can keep freshness, maintain the umami flavor, and avoid the loss of nutrients. If the red beans get damp, they will easily deteriorate and cause insects, so they should be kept dry and placed in a sealed jar.

Put red beans (all granular grains are acceptable) in a clean, dry beverage bottle. When you put it in for the first time, be sure to pack as much and as solid as possible. Tighten the lid and store in a cool place. After storage, you can open the lid and eat it after three to five days. Just tighten the lid in time after each use.
