1 Wash the sweet potatoes, steam them in an electric cooker and peel them off.

2. Cut into thin slices about 0.4 cm and spread them on baking paper.

3. Bake in the oven 140 degrees for about one hour (depending on the time of individual oven).

4. Take out and finish the delicious dried sweet potato.

Second, the practice of dried sweet potatoes

1, cellar

Everyone knows that the sweet potato in winter is the sweetest, because the sweet potato just produced has a lot of water, so here we put the new sweet potato in the "sweet potato cellar" and wait until winter to gradually take it out.

2. Steam in the pan after cleaning.

After cleaning the sweet potatoes, steam them in the pot, just like the steamer bag.

3. Peeling

After steaming, it is peeled. The peeling process will filter out the bad sweet potatoes, leaving only the big and good ones.

4. Slice

Then sliced one by one by hand, dried far away from the ground, and dried for 3-4 days. This process is very important, because the longer the drying process, the more starch is converted into sugar, and the sweeter the sweet potato is.

5. Dry

The sweet potato slices are evenly packed in a special drying net for ventilation and drying, which normally takes 3-4 days. When the sugar is naturally generated and basically dried, it is stored, and the drying time determines the sweetness of dried sweet potatoes.

Third, matters needing attention

1. Sweet potatoes should not be eaten too much at one time, and should not be eaten on an empty stomach. Sweet potato contains an oxidase, which easily produces a large amount of carbon dioxide gas in human gastrointestinal tract. For example, if sweet potato is eaten too much at one time, it will make people feel bloating, and eating it on an empty stomach will stimulate gastric acid secretion and make people feel heartburn.

2. The deficiency of sweet potato is the lack of protein and fat, but today people are rich and no longer take sweet potato as the staple food, and its lack of nutrients can be supplemented by other diets. Therefore, it is the most scientific way to eat a few slices of sweet potato after each meal.

3. Sweet potato should not be eaten with dried persimmon: if eaten at the same time, the sugar in sweet potato will ferment in the stomach, which will increase the secretion of gastric acid and precipitate and condense with tannin and pectin in persimmon, which will make the stomach feel uncomfortable.
