"Hot and sour powder" is one of the traditional snacks widely circulated between urban and rural areas in Sichuan, and it has been loved for a long time because of its low price and good quality. "Hot and sour powder" is mainly made of sweet potato powder. There are two kinds of "hot and sour powder": one is "gouache", which is made of sweet potato starch; The other is "dry powder", that is, dry powder strips processed into powder strips. Because the hot and sour powder made of dry powder strips is relatively simple and convenient, dry powder is mostly used all over the country, while the preparation operation of "gouache" is relatively complicated. The following describes the process of making gouache (dry powder can be made directly by families: the method is to soften the dry powder with water).

Raw materials: 5000 grams of sweet potato starch, 35-40 grams of alum, and 0/25-/0/30 grams of cooked glutinous rice paste.

Note: The cooked sweet potato starch is first dispersed with clear water, then washed with boiling water, and stirred into a thin paste, which is commonly known as "cooked sweet potato starch".

Making:

1, grind alum into fine powder, add water100g and stir well to make alum water.

2. Pour the cooked paste into the basin, add sweet potato starch, 2000g of clear water and alum water, and knead it into a powder ball with moderate hardness for later use.

3. Use a large aluminum ladle to insert it into a hole the size of a soybean, put the dough into the ladle, pat it with your palm to make it leak into a boiling pot and cook it, then pick it into cold water and let it cool to get the gouache.
