Yes, it's ok to cook corn porridge at night and eat it the next morning. Because that's your thermos. The rice cooker won't work without heat preservation, and it will be cold the next day. If your rice cooker is well insulated, it's still the same, like being careful. It depends on whether your rice cooker is good or not. Me too. My rice cooker is just very good. The rice cooked on the first night is the same as that cooked at ease the next morning, and the degree of heat preservation is very good. I can't do it with it. The rice cooker, the rice cooker, he didn't take me the next morning. It was not delicious.
