Cook eight-treasure porridge in an ordinary rice cooker: wash the eight-treasure porridge for later use, and then feed it after the water is boiled. The ratio of material to water depends on how thick porridge you want to cook, like the filling concentration. According to my experience, for two people, half a can of ingredients (the tin can of eight-treasure porridge sold) is enough, put about 2 liters of water, cook for an hour, and water (in order to prevent overflow after opening, you can sit back and relax).
Cooking eight-treasure porridge with high-pressure rice cooker: put water and eight-treasure porridge into the pot in proportion, soak for 30 minutes, then adjust it for 40 minutes, and then turn on electricity. If you don't soak it, add another 5 minutes, and you can eat eight-treasure porridge in an hour. If you eat sweets, you can also put sugar and eight-treasure porridge together.
