Red sweet potato

Baked sweet potato, also known as baked sweet potato and roasted sweet potatoes, is especially popular among Shanghainese. Especially in winter, baked sweet potatoes from foreigners can be seen everywhere on the streets of Shanghai. Because the sweetness of baked sweet potato increases, it is especially sweet, and you can smell the burnt fragrance of baked sweet potato far away. In recent years, a new way of eating is occasionally seen in the streets of Shanghai, that is, frying sweet potatoes in oil pan, crispy on the outside and soft on the inside, sprinkled with a little sauce, which is very delicious.
