The method of freezing Portunus trituberculatus for boiling crabs is as follows:

Wash the frozen sea crabs, boil the water, put the crabs in when the water boils, about 10- 15 minutes, wait until the crabs float, cook for 2-3 minutes, and take them out after cooling. You can dip it in the sauce made of garlic and ginger, or put the soup in the refrigerator and cook the noodles later.
