Selection of sweet potato
First: Look at the shape of sweet potato.
Sweet potato has two shapes, thin, long, round, short and fat. Among them, the thinner sweet potato is nicknamed "male sweet potato" among the people, while the short and fat sweet potato is called "female sweet potato". The slender shape of "male sweet potato" looks good after being cut off, mainly because the sugar content is much higher than that of "female sweet potato".
"Mother Sweet Potato" is fat and not suitable for roasted sweet potatoes, otherwise it will look familiar on the outside and raw inside. "Sweet potato mother" is more suitable for cutting and boiling sugar water.
Second: Look at the surface soil.
When we bought sweet potatoes, we found that sweet potatoes would stick to some soil more or less, but the soil was different in dryness and wetness. We should choose those sweet potatoes whose soil feels dry, because this type of sweet potato has been placed for some time since it was unearthed. After a period of drying, the water content of sweet potato will be appropriately reduced, the sugar concentration will become higher, and it will taste sweeter.
Third: look at the epidermis.
Some sweet potatoes are left for too long, and the water is basically lost, and the skin of sweet potatoes will wrinkle. Sweet potatoes stored for too long may go bad, so it is not recommended to buy them. We should choose to buy some sweet potatoes with smooth skin and no wrinkles. These sweet potatoes are fresh, full of water and sugar, and the cooked taste will be sweet and delicious.
