1. First, soak the fresh shrimp in salt water for 3 to 5 minutes, and then pull out the whole shrimp head. The head of shrimp contains the digestive system of shrimp, and the bacteria content is high, so it is inedible. Then use a toothpick to pick out the shrimp line on the shrimp tail. There are some tips for removing shrimp lines. We start counting from the head of prawn and see the third curved joint of prawn, which is the white part.

2. From there, you can pull out a black shrimp line with a toothpick, and we have to gently pick this part of the shrimp line, and then slowly pull out the shrimp line by hand. When pulling the shrimp line, the strength should be slightly uniform to prevent the shrimp line from breaking halfway, otherwise it will be more difficult to pull the shrimp line again.

2. Finally, cut off some small claws on the tail and abdomen of the shrimp, so that the shrimp can be handled easily.

Precautions for buying shrimp:

1, when we go to buy prawns, we touch their bodies with our hands. At this time, you feel that prawns are sticky to the touch, so such prawns are likely to be harmful to our health after being bought by snakes. Therefore, it is not recommended to buy such prawns.

2. When buying prawns, you can also look at the surface of prawns. If we find that the shrimps of prawns have fallen off, then such prawns are likely to be left for a long time and taste worse, so there is no need to waste money on something that tastes bad.

3. You can also observe the shrimp head when buying prawns. If you find that the shrimp hair is yellow, then this kind of shrimp is not fresh and it is not recommended to buy it.
