Prepare a big basin, add clear water into it, add a proper amount of salt, a bottle of white vinegar and baking soda powder (50g), and then pour crayfish into the basin after stirring evenly. During the soaking process, you will find that the dirty things of crayfish will run out slowly and the water will become more and more turbid, which shows that our homemade "cleaning agent" has worked.
Rinse the crayfish with clean water until the water becomes clear. If you are not at ease, you can pick up a few crayfish at random and check them. You will find that this method is no different from the brushed crayfish. It is really simple and effective, and it is very easy and worry-free. The rest will be cooked according to your practice.
Function of baking soda powder: Baking soda is a kind of food additive, which is often used when making pasta. Baking soda itself is alkaline and has a slight cleaning effect when mixed with water, so the cleaning effect will double with the reaction of white vinegar, so there is no need to worry about residue.
