I went to a friend's house before, and the problem of choosing shrimp skin was mentioned in the chat. His father told me that the whiter the shrimp, the better. To sum up, there are three kinds of shrimp skins, try not to buy them. As a result, he also taught me three simple and easy-to-use tips to buy shrimp, saying that if I learn these three tips well, I will definitely buy top grade. Later, I heard from a friend that his father was actually a fisherman with 20 years of fishing experience. No wonder he knows so much.
Look at the appearance. If you buy shrimp skin, these are broken and dark in color. Obviously, the quality is not very good. We can identify all these. But some businessmen will promote some yellow ones and say yes.
Salt-free shrimp skin is of high quality. Now you must pay attention. Only people who don't understand will be cheated by him. This kind of shrimp skin is probably smoked with sulfur. The high-quality shrimp skin is purple in color and completely transparent, but it is not a single thing. The whiter the better. On the premise of detailed beginning and end, the higher the block, the fresher the shrimp body.
In addition, depending on the variety of shrimp, the color tone will be somewhat different. Shrimp skin made from Bohai shrimp is relatively white and small. The skin of South China Sea shrimp is dark red and relatively large.
See what you are doing, everyone must learn to shop, and use the four-in-one purchase method of seeing, touching, mouthing and smelling. Put it on the shrimp skin, that is, grab a handful of shrimp skin with your hands, hold it hard, and it will spread out immediately after being released, indicating that it is still relatively dry. If it is packed in groups, it means that the water content is high. Even if it looks round and the price is high, try not to buy it, because this kind of shrimp skin is cheap at first glance. In fact, the water content is weighed by a scale, which is not worth calculating!
The ultimate trick to smell and taste is to smell and taste directly. This method is simple and rude. If you like its taste, you will buy it. Don't buy it if you don't like it. There are many levels for your reference. First, take a handful of dried shrimp skin and put it near your nose to smell it. If what you smell is not the aroma of seafood, it is an unspeakable smell, which is probably smoked by formaldehyde or sulfur indoors. Remember not to buy this at this time; Then put it in your mouth and taste it. The lighter the taste, the better the quality and the saltier the quality.
