(1) Blanch the shrimps with boiling water or boiling oil until raw, cool them and put them in the refrigerator, so that the red color of the shrimps can be fixed and the flavor can be maintained for a long time.
(2) Peel the shrimps into shrimps, put them in an ice bowl, add a proper amount of water, and then put them in the refrigerator for quick freezing, so that the quality, taste, quantity and color of fresh shrimps will not be affected even if they are stored for a long time.
Steam it as well as possible, cool it, put it in the freezer for quick freezing, and then heat it when eating. Generally speaking, it is best not to eat shrimps that have died for more than 2 hours at room temperature. Fresh Pippi shrimp can last for 3 hours under natural conditions after being bought back. I suggest you eat it as soon as possible during this time.
The frozen Pippi shrimp in the refrigerator smells stale or bad, and it can still be eaten. If it smells bad, don't eat it, so as not to spoil your stomach.
