step 2: peel and then clean.
in step 3, cut into pieces about one centimeter thick and steam in a steamer for about ten minutes. Don't steam for too long, just cook it.
step 4: after steaming the sweet potato, uncover the lid, let the sweet potato cool completely, then take it out and put it on a clean dustpan or drying net. Be sure to cool it thoroughly before taking it out, otherwise it will rot easily. Occasionally turn the sweet potato over during the drying process.
step 5 if the sun is fine, after a day of sun exposure, the sweet potato skin becomes dry and tough, and this state can be cut into strips.
Step 6: Cut the sweet potato pieces into even strips. If it is easy to break when cutting, you can wait for the sweet potato pieces to dry a little before cutting.
put the sweet potato strips cut in step 7 evenly in the dustpan, so it will take about two days to dry. Remember to turn them over halfway.
step 8: the water is dried to 7% to 8%, so it tastes tender and chewy. You can store it in a sealed bag and take it with you. You can also add some when cooking rice, which is also very delicious.
