1. If the shrimp is steamed as a whole, boil the water and steam for 5 minutes. Because the protein content of shrimp itself is very high, almost all of them are protein, but heating with shell will slightly hinder the steaming of the whole shrimp, so the steaming time should be controlled at 5 minutes.

2. If the shrimp is steamed, boil the water and steam for 4 minutes. Because the water in shrimp meat will evaporate more easily after the head is removed, the heating of shrimp meat will be obviously accelerated, and it can be eaten after steaming for 4 minutes.

3. If the shrimp is steamed on the back, boil the water and steam for 3 minutes. Because the meat inside the prawn is opened, the heating surface will be greatly improved, and the thickness of the whole prawn will be divided into two, so the steaming time will naturally be significantly shortened, and steam is generally used for about 3 minutes.

4. If the shrimps are steamed, boil the water and steam for 3 minutes. Although the shrimp is completely shelled, the shrimp meat is still thick, and the steaming time is the same as that of the open-backed shrimp. It is recommended to steam for 3 minutes before eating.
