knack for cooking

1, the time for cooking in the microwave oven is adjusted according to the size of sweet potato and the power of the microwave oven. The power of my microwave oven is 750W W.

2. The amount of milk in the material can also be adjusted according to the variety of sweet potatoes. Some sweet potatoes are particularly dry, so it is necessary to increase the amount of milk. It is recommended to use red hearts for sweet potatoes, which are rather waxy.

3, cheese, I use the existing mozzarella cheese at home, you can also use the flaky cheese in the supermarket.

4, this dessert should be eaten hot, and the taste will be greatly reduced when it is cold.
