There are two kinds of sweet potatoes that we can buy every day: white sweet potato and yellow sweet potato, among which white sweet potato is much drier than yellow sweet potato. When we steam sweet potatoes in a steamer, we can obviously feel that white sweet potatoes are powdery, while yellow sweet potatoes are soft, but even yellow sweet potatoes will be very dry.
Therefore, in addition to the sweet potato itself can not be dry baked, it is also related to the baking method and time. If the sweet potato is baked in the oven like this, it is likely to be dried sweet potato after being taken out.
I baked sweet potatoes at home and experienced the same failure as you. Among them, several methods are preferred. Suitable for baking sweet potatoes in oven and microwave oven respectively.
1. When baking sweet potatoes in the oven, in order to keep the moisture on them, if the sweet potatoes are exposed in the oven, it is easy for them to lose moisture in the high temperature environment of the oven. At this time, you can choose sweet potato with more moisture in the yellow heart, wash it, keep the skin moist, wrap it tightly with tin foil, and then preheat the oven at 220℃ 10 minute and bake it.
2. If you want to cook sweet potatoes without tin foil, clean them and steam them in a steamer for ten minutes, then take them out and bake them on the grill of the oven for half an hour.
3. If there is no oven at home, only microwave oven partners can cook baked sweet potatoes at home. Wash the sweet potato, wrap two layers of napkins on the surface of the sweet potato, soak all the napkins in the microwave oven, bake with high fire for 7-8 minutes, and then take out the semi-dry napkins soaked again. The sweet potato can be cooked thoroughly over and over again, and it tastes like roasted sweet potatoes, and it won't dry at all.
These are some of my experiences in baking sweet potatoes. I hope I can help you who also like to study food. Thank you!
