Red beans are soaked in water overnight in advance, so they can be cooked for 20 minutes after SAIC. No soaking, they need to cook for 30 minutes, SAIC. In addition, the firepower of boiling red beans will also affect the time required. The greater the firepower, the shorter the time required. Conversely, the smaller the firepower, the longer it takes. It should be noted that, for the sake of safety, after SAIC, the firepower for cooking should be reduced by half. If you want to save energy and don't mind spending more time, you can choose SAIC and continue cooking for 5 minutes, then turn off the fire for a while, and red beans can also become very mushy.
