1.
Do not peel the sweet potato, wash it, put it in a special bowl for microwave oven, cover it tightly, and heat it for three minutes without adding water.
2.
If you bake two or three sweet potatoes at the same time, the time should continue to increase, two for five minutes and three for six minutes.
3.
If you find that the sweet potato heart is still a little hard, throw it in and continue for about a minute. Too long will dry the sweet potato.
