According to the query of Kyushu Drunk Catering Network, blanching will make the meat quality of shrimp old and affect the taste. When making frozen shrimp, just thaw the shrimp and put it directly into the pot. When cooking frozen shrimp, be careful not to thaw too much at a time, just eat as much as you want. Non-frozen shrimps that can't be eaten can't be kept for too long, at most for one day, and shrimps are easy to go bad.
