Tools/ingredients: metapenaeus ensis, toothpicks.

1, break the shrimp line, count from the tail of the shrimp, go to the second section, and insert a toothpick.

2. Pick off its shrimp line first. After the shrimp line is picked off, bend and press the last section of metapenaeus ensis to ensure that the downline is in the black part of the last section and move to the front of the second section, which is convenient for picking out the shrimp line.

3. Then you can see that there is a mass of yellow and black garbage wrapped in film in the back of metapenaeus ensis's head. At this time, pick it out with a prepared toothpick and take it out, so that you can also take out the shrimp line. This method is relatively simple and practical.

Why go to the shrimp line:

Shrimp thread is the body tissue of shrimp. Generally speaking, the digestive system of shrimp, such as intestine, tends to accumulate heavy metals, so the shrimp line should be pulled out before cooking, and there is waste in the shrimp line on the back of shrimp.

Shrimp thread removal is not only because there are dirty things in the digestive tract of shrimp, but also because it 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. After cooking (cooking), the bacteria in the shrimp line will be killed by high temperature, which is safe, but it may taste worse and have a rust smell, so it will be removed better.
