Step 1: First, pick up a ripe crayfish, which can be divided into male and female by its abdominal position. If there are several hard calves between the head and the body, it can be judged as a male shrimp. On the contrary, if there are no hard calves, it is a female shrimp. Generally speaking, the female shrimp will be more delicious.

Step 2: Distinguish the growth environment of crayfish before serving. You can observe the respiratory gills by opening the inside of the head shell on both sides. If it is clean and white, the water quality in the culture environment is better. If it is black, it proves that the water source of culture is polluted.

Step 3: Hold the shrimp body gently with one hand and put the other hand on the head of the shrimp, and then you can separate it by turning the hand of the shrimp body gently. At this time, you can see that the shrimp yellow is attached to the top position of the just separated shrimp body. The taste of the shrimp yellow is delicious and it is also the most precious place for crayfish.

Step 4: Eating the body parts and tails of crayfish can slowly crush the shells on both sides down along the lines, so as to avoid injury and make it easier to peel them by hand.

Step 5: The shrimp line plays a filtering role just like the breathing gills, so many bacteria must be removed when eating crayfish. The correct way to eat is to hold the front and back of the yellow position of shrimp with both hands, and gently pull open the shrimp line that will appear in the middle of the fleshy body. It is usually black, just pick it out or pick it out with a toothpick.
