Recipe practice:

1. Wash the sweet potato, put water in the pot, and boil it for about 10 minutes. Insert chopsticks to see if they are cooked.

2. After cooking, take it out and put it in a basket to cool.

3. Cut into strips and dry them in the sun or in a ventilated place.

4. Turn it at least once a day until it is completely sunned or dried. Personally, I prefer to eat soft food, which depends on my personal preference.

5. Wrap the food and put it in the refrigerator.
