1. Generally speaking, it is not recommended to eat overnight dishes, but the weather is very cold this season, and the food will not go bad overnight. Sweet potato syrup can be used overnight.

2. Personally, I like to cook rice porridge with sweet potatoes, that is, peel the sweet potatoes and cut them into thin slices, wash the rice and millet, dig out the red dates and cut them into pieces, then put them in the rice cooker, sprinkle with white sugar, put some medlar and water in, and stew them for 20 minutes on low fire.
