Sanmei Sanpi is a traditional snack in Hunan, and its main raw materials are pigskin, peanut butter and sugar and garlic. In the production process, the pigskin is cut into blocks, then boiled in hot water and the hair and fat on the surface are removed, then marinated in vinegar water and soaked pepper segments for a period of time, and finally fried to golden brown and dipped in peanut butter and sugar garlic. Sanmei Sanpi is crispy, spicy and delicious, and it is an important part of food culture in Hunan.

In some places in Hunan Province, Sanmeisanpi is also called "spicy crispy skin". In addition to the common peanut butter and sugar garlic, some diners will choose to dip in other condiments such as coriander, sesame sauce or bean curd, which will make the taste richer. In addition, glutinous rice flour will be added to every three skins in some places, and the fried taste will be more tough. Either way, it is full of local food culture in Hunan.

Sanmei Sanpi is a household name in Hunan. It can be seen not only in local food stalls, but also in some large supermarkets. Many tourists come to Hunan to try this historical food and feel the unique charm contained in it. Although it is a bit cumbersome to make, the three-for-three skin is still deeply loved by Hunan people and tourists, and it also reflects Hunan's unique contribution to food culture.
