1, flour washing precipitate
First, put the bought crayfish into a big pot. First, simply wash off the sediment on the surface with clear water, then add a proper amount of flour to the basin to help clean the sediment on the surface of crayfish with the viscosity of flour.
If you are not in a hurry, you can soak crayfish in water for a day. The life of crayfish is tenacious, even if it is soaked for a day, it will not die. After soaking, crayfish will spit out impurities in their bodies. At this time, cleaning is more convenient.
2, salt, vinegar soak sundry
Secondly, add a proper amount of salt, stir well, and let it stand for half an hour before washing. You can wear gloves when cleaning to prevent being caught by crayfish pliers. After filtering out the dirty things, add an appropriate amount of white vinegar to soak for at least one or two hours, filter out some impurities spit out by crayfish, and wash each crayfish with a small stream.
Step 3: Brush
Then prepare a big clean basin, brushes and scissors, pour clean water into the basin, put on rubber gloves, and brush the head, abdomen and tail of each crayfish with a brush. Crayfish can be brushed several times, then carefully washed with clear water and put into a basin for later use.
4, scissors to deal with internal organs
Finally, the head of the brushed crayfish is treated with scissors. The scissors cut a hole at a 45-degree angle in the third part of the head of the crayfish, which contains black cysts and yellow shrimp yellow, and clean up the undigested dirty things of the crayfish. When cleaning the head, the gills on both sides of crayfish can be removed together to avoid accidentally eating dirty things of shrimp yellow when eating.
When processing shrimp line, we can turn the belly of crayfish up, find the crustacean in the middle of the tail of crayfish and hold it down, then twist the tail for half a turn and gently pull it out, and the shrimp line of crayfish will be processed.
