2, wash the sweet potato, be sure to wash the mud on the surface of the sweet potato. Without peeling, put it directly into the pot, then add water and cook for 30 minutes. The cooking time depends on the size of the sweet potato, as long as the sweet potato can be cooked. In addition to cooking this cooking method, of course, you can also cook sweet potatoes by steaming.
3. After the sweet potato is cooked, peel it, cut it into pieces, slice it, or change the knife and cut it into strips. This can be decided according to your own preferences. There is no rule about what shape it must be cut into.
4, take a clean dustpan, and then put the cut sweet potatoes into the dustpan, which can be placed densely. Because in the process of drying, the moisture of sweet potato slices will be evaporated, so the spacing will become larger and larger, so there is no need to worry about placing them too tightly at first.
5, sweet potatoes exposed to the sun for a few days, basically it is ok. Of course, this is a lazy practice. If you want dried sweet potatoes to achieve the effect of being soft in the middle and hard in the middle, in fact, you have to put them back into the pot and steam them again after 2 days of drying. This process is called secondary re-steaming. The purpose of this is that re-steaming can make the water in sweet potato slices evaporate faster and taste sweeter. Steam the dried sweet potatoes in the pan for 10 minutes, and then dry them in the sun again.
6. After the dried sweet potatoes continue to be dried in the sun 1 day, they have to be steamed for the third time. Take back the dried sweet potatoes, steam them in a water pan for 15 minutes, and finally expose them to the sun again 1 day. The purpose of doing this is to make the dried sweet potatoes shape, and the dried sweet potatoes are hard in the sun, and then they can be softened by steaming in the pot. After steaming, put the dried sweet potatoes on the dustpan again and sun them for one day, so that the dried sweet potatoes are finished.
