1. Clean the beans and soak them in clear water for 2-3 hours. (If you don't make an appointment in advance, the soaking time should be about 8 hours. )

2. Put the soaked beans into the electric pressure cooker, wash the other rice, put it into the pot and add enough water.

3. Calculate the time and agree on a fixed time. I made an appointment for seven hours, and then I began to cook porridge. You can go to bed when you make an appointment. Wake up in the morning with the smell of porridge, wash it, boil it and eat it. It's beautiful.
