1, choose the right sweet potato. Dried sweet potatoes after the autumn harvest are better to eat. Red-hearted sweet potatoes selected in advance can be placed for one month to control moisture.

2. After the sweet potato is washed and peeled, you can cut it into smaller pieces, put it in a steamer and steam it with strong fire. When it is cooked, simmer it 15 minutes.

3. After the sweet potato is slightly cooled, cut into sweet potato slices with a thickness of about 0.5cm.

4. Place the cut sweet potato slices on the drying rack one by one.

5. Put the sweet potato slices in a sunny and ventilated place to dry, and turn them over from time to time.

6. Put the dried sweet potatoes into a closed container and put them indoors. After half a month, frost will grow.
