The younger shrimp, whose shell is blue, is called green shrimp; When crayfish grow to a certain number of days, it will turn red because the pigment in the shrimp shell gradually precipitates;
Crayfish cultured in places with little clear mud in water environment have blue shells, while crayfish cultured in places with much dirty mud in water environment have red shells.
The difference between green shrimp and red shrimp lies not only in the color of shrimp shells, but also in many other aspects:
The meat quality is different: the green shrimp meat is tender and loose, while the red shrimp meat is elastic and firm;
The meat output is different: for a crayfish with the same net weight, the meat output of green shrimp is greater than that of red shrimp; However, the pliers of green shrimp are basically small, and the meat in the pliers is not as much as that of red shrimp;
Different shells: the shell of green shrimp is thin and soft, and the shell of red shrimp is hard and thick;
Prices are different: before April, that is, the price of crayfish was higher than that of red shrimp, and after May, the price of red shrimp was higher than that of green shrimp;
Different cleanliness: green shrimp is relatively clean as a whole, and red shrimp has more stains, which is more complicated to clean;
Different heads: the head of green shrimp is often smaller than that of red shrimp, which also leads to less yellow shrimp than red shrimp.
Which is better, green shrimp or red shrimp?
Which one tastes better, green shrimp or red shrimp, is discussed according to the different requirements of everyone for meat quality:
Shrimp is often easier to taste and tender, suitable for the elderly, children, or friends who care about taste but don't care much about taste;
Because red shrimp is dense, it is often not as deep as green shrimp after cooking, and the overall taste is closer to the original taste, mainly relying on the juice attached to the surface of shrimp. However, because of its large size, red shrimp is more enjoyable to eat, and shrimp yellow is also rich.
How to choose crayfish when buying
Try to choose green shrimp before April, because green shrimp is the crayfish in the season, while red shrimp is the old shrimp in the last breeding cycle, with a thick and hard shell and no meat;
After May, you can buy green shrimp and red shrimp according to your personal preference.
When choosing crayfish, in principle, choose the ones that are particularly fierce and not black (dark in color). Black crayfish are often morbid, so try to avoid them.
If conditions permit, you can pick one by one, then pinch the abdomen and head to choose the best, full and elastic.
