Roasted Sweet Potatoes
1.
Wash the sweet potatoes.
2.
Moisten kitchen paper with water and wrap the sweet potato.
3.
Bake in the oven for about 30 minutes. (My oven is a small oven that cannot be adjusted in temperature. The baking time depends on the temperature of the oven at home.)
4.
It's cooked and ready to eat.
Tips:
When taking the test, be sure to wrap it with wet kitchen paper to better preserve the moisture of the sweet potato.
