The method of roasting sweet potatoes is as follows:

1. Wash the sweet potatoes and set aside. Do not peel them. It is best to wash them with a toothbrush. Rinse and brush them at the same time. This will wash them more cleanly. Then drain the sweet potatoes. a lot of moisture.

2. Cover the grill with tin foil and place the washed sweet potatoes on the tin foil.

3. Preheat the oven at 210 degrees for 10 minutes, then put the sweet potatoes into the middle layer of the preheated oven and bake at 210 degrees for about 80 minutes (the baking temperature and time are for reference only, depending on the size of the sweet potatoes and how much to adjust).

4. Bake until the sweet potatoes ooze sugar juice.
