Specific practices
1. Wash the sweet potato, peel and slice it, and steam it in the pot.
2. Mash the steamed sweet potatoes into mud! Add a small piece of butter and cheese while it is hot and stir well.
3. Put the mashed sweet potato into an iron box, then sprinkle a thick layer of cheese crumbs on it, put it into an air frying pan, and bake at 180 degrees for 10 minutes. A simple baked sweet potato with cheese will be fine!
