The first reason is:
To tell the truth, most of the sources of shrimp tails are not peeled off by live shrimps, but crayfish that have lost their vitality. These crayfish are also bought by stall owners, and they will definitely not throw away those inactive crayfish directly.
Then you can only take off the shrimp tails of these crayfish and sell them as fresh shrimp tails. When they sold these shrimp tails, they shouted slogans and peeled a batch of shrimp tails for the convenience of eating crayfish.
The second reason is:
The taste of crayfish, when we eat crayfish, only the whole crayfish is delicious. If we only eat shrimp tails, you will feel that eating crayfish is much less fun, especially the shrimp yellow in the head of crayfish, which is also delicious.
Of course, when we deal with crayfish, we must cut off the head of crayfish first, and it is best to leave only the shrimp yellow part. Moreover, when we cook crayfish, the taste is heavy, so at this time, if you eat shrimp yellow, you will feel special.
The third reason is:
Where is the shrimp tail in the vegetable market? In fact, most of these shrimp tails sold in the vegetable market are for hotels, and few people buy them. The hotel bought these shrimp tails for the convenience of cooking. Sometimes, most of the shrimp tail dishes you eat in hotels are made of this kind of shrimp tail.
Last tip: Although crayfish is delicious, it is not recommended for everyone to eat more, especially those with bad stomach. Crayfish is not recommended. After all, crayfish tend to have a heavy taste, and if the taste is heavy, then the stomach will react.
