The key is the size of prawns. Generally speaking, medium-sized prawns can be cooked for 1 to about 3 minutes, not more than 3 minutes. After the water is boiled, put the prawns in, keep the heat, and it's almost the same when you see the prawns turn red and roll.

There are many cooking methods for prawns, among which boiled prawns can best retain their original ecology. Boil prawns with tap water, and then use seasonings such as soy sauce, sugar and ginger slices to adjust the juice and dip it in the cooked prawns, so that it is not easy to lose the umami flavor of prawns due to cooking, which is convenient and delicious.

When choosing shrimps, it is best to choose those that sink to the bottom of the pond, and most of them float to the surface because of lack of oxygen. However, you should also pay attention to the shrimp floating on the bottom of the water. Some dead shrimps will also sink to the bottom of the water, so you should look carefully to see if they are fresh.

Shrimp is transparent, bright and freshest. If the body part of the shrimp is found to be white and its activity decreases, it proves that the life of the shrimp is coming to an end.

Choose shrimps with blue head, white belly, transparent back, complete body, dense shell, clear shell, tight muscles, elastic body and dry and clean body surface.
