Dried shrimp, as its name implies, is the finished product of fresh shrimp dried in the sun, which is rich in vitamins and nutrients.
Shrimp still contains a lot of bacteria, which is very unsanitary. Shrimp skins are made by directly drying live shrimps, and some shrimp skins are not very hygienic during drying. So after you get the shrimp, you'd better wash it and cook it with other dishes at high temperature. At the same time, the black line on the back of the shrimp needs to be pulled out, because that black line is the intestines of the shrimp, and even if it is dried, the intestines of the shrimp cannot be eaten. Of course, shrimp heads are even more inedible.
Besides, the common shrimps are salty, so it is unbearable for ordinary people to eat them directly. It needs to be soaked in warm water for about an hour, and then cooked with various seasonings.
