Hot baked sweet potatoes on the street are very popular in winter. If you are worried that it is unsanitary to bake sweet potatoes on the street outside, you can bake them in a household microwave oven. Generally, sweet potatoes will be cooked in the microwave oven for 8- 10 minutes, but the time should be adjusted according to the size of sweet potatoes. If the time is up, the sweet potato can continue to be baked until it is cooked.

Microwave oven is a kind of high frequency electromagnetic wave. Microwave ovens heat food through microwaves emitted by magnetrons. The magnetron in the microwave oven can generate microwaves with a vibration frequency of 2.45 billion times per second. This kind of microwave can penetrate 5 cm inside the food, making the water molecules in the food move with it. Water molecules generate huge heat energy during the movement, so food is heated.
