1, if you buy live river shrimps from the market, you can put a small amount of salt in the water, soak the river shrimps in 10-20 minutes, so as to discharge the filth, and then rinse them with water.
2. If there are higher requirements for the cleaning of river shrimp, you can brush the belly of river shrimp with a small toothbrush. If it is a relatively clean river shrimp, this step can be omitted.
3. The rectum of river shrimp is located in the back, and it is full of digestive residues. If it is not cleaned, it is easy to be eaten in the stomach. Removing the shrimp line is a very important part of washing shrimp.
Shrimp removal line:
1, cut the shrimp head and cut it down from the shrimp brain at an angle of 45 degrees.
2. Pick out the shrimp brain with scissors. Black brain and red blood came out.
3. Next to the front of the shrimp brain is shrimp yellow, which is a good thing. If there is yellow, be careful to keep it as much as possible when picking it.
4. Gently pull out the shrimp brain, and some shrimp intestines will be pulled out.
5, cut the shrimp tail, if you don't want to look good, cut the shrimp tail, and cut it with a little tail meat, because there may be sphincter muscles here that can't be squeezed out without cutting more, but it will crush the shrimp.
6. Squeeze the shrimp intestines, pinch the shrimp back with your index finger and thumb, and exert force on the tail, and the shrimp intestines come out. Go on. Look at the mud sausage squeezed out.
The shrimp line is the digestive tract of the shrimp, on the back of the shrimp. Some are very dark, some are very light, and they are almost invisible, which is related to the dirty things in them. Shrimp line will affect the taste, so some people will remove it.
Shrimp thread removal is not only because there are dirty things in the digestive tract of shrimp (this is the same as the reason we remove fish gills and crab gills), but also because shrimp thread affects the taste, especially when steamed in white and braised in wine. Shrimp thread contains bitter substances, which will mask the sweet taste of fresh shrimp under the action of heat. If it's spicy and stir-fried, it doesn't matter whether you go to the shrimp line or not because of its strong flavor.
