When cooking shrimp, it is generally recommended to cook with hot water, because the appearance of boiled shrimp becomes ripe quickly, which protects the vitamins in shrimp meat and kills the enzymes in shrimp meat at this time. However, shrimp cooked in cold water will lead to the aging of shrimp meat, and cooking for too long will destroy the nutrients of shrimp and lose the umami flavor of shrimp meat.

If the shrimp is fat, boil it for another five minutes; If the shrimp you buy is small, shorten the cooking time, about 2 to 3 minutes. Cooked shrimps can be quickly cooled in cold water for 20 seconds, and then taken out to control the water content and put into a plate, which can make the meat quality of shrimps more tender and refreshing.

Dry body surface: Fresh shrimps are clean in appearance and dry in hand. However, when the shrimp body is about to deteriorate, the granular cells secreting mucus in the lower layer of crustaceans disintegrate, and a large amount of mucus penetrates into the body surface, which feels greasy. If the shrimp shell sticks to your hands, it means that the shrimp has gone bad.

Bright colors: Different kinds of shrimps have slightly different colors. Fresh shrimps, rock shrimps and grass shrimps are blue, shrimps caught in the sea are pink, and bamboo shrimps and new shrimps with knife forehead are black and white with a slight pink color. If the shrimp has black hair, it is stale shrimp, and the whole shrimp is dark and not bright, which means it has gone bad.
