The method is as follows:
Soak sweet potatoes in clear water and wash them.
Don't drain the sweet potato, put it directly on the paper in the kitchen, and sprinkle some water in advance.
Wrap the sweet potatoes and put them all in.
Then put it in the microwave oven, keep the fire for 3 minutes and turn it over for 2 minutes.
If it doesn't feel soft, you can continue baking.
