Prawn is a very popular seafood, with tender meat and delicious taste, but the price is not cheap. The supermarket wants 36 yuan 1 kg, and if it is not cooked well, the ingredients will not be delicious.
The easiest way to cook prawns is to boil them in water. You can eat them with water, but some people can't cook them well. The shrimp meat is not tender, and it has a strong smell, and the shrimp head turns black after a while. What is the reason? The chef said, it's no use! I'll teach you how to cook boiled shrimp.
Why does the shrimp head turn black?
As we all know, both crabs and shrimps are red after normal cooking. If they turn black after cooking, there are two situations:
1, the quality of prawns is not good, they are not fresh, such as dead shrimps and frozen shrimps, and there are still undigested food residues in the body, which are easy to turn black after cooking.
2. The prawn undergoes an enzymatic reaction after being heated. The prawn contains tyrosinase, which will form quinones at a suitable temperature, and then turn into eumelanin, brown melanin and other substances, and the prawn will turn black.
How to cook boiled shrimp so that it won't get old, tender and tasteless? The chef said that as long as you master three skills, you can ensure that the shrimp meat is soft and tender, and there is no fishy smell. Let's share the skills with you.
Skills of boiling shrimp
1, buy and cook now
Although I bought live shrimps, they were all packed in shopping bags. Under the condition of lack of oxygen, the residue could not be discharged, and the shrimp head would turn black. At the same time, too much contact between hands and prawns when washing prawns will cause enzymatic reaction and the head of prawns will turn black. Therefore, it is best to buy and cook prawns now and simply rinse them.
2. Cook in cold water
What is the boiled shrimp boiled in? Some people say cold water, while others say boiled water. Which statement is correct?
If you use boiled water, although it turns red, the shrimp meat is not completely cooked, and it is "half-cooked". If you continue to cook for a while, it will be cooked, but the taste will become old, not fresh and tender, and there is still a lot of fishy smell.
How to cook prawns? The chef said, pour the right amount of cold water into the pot, add the right amount of onion, ginger, salt and cooking wine, and then cook over fire. After boiling the floating foam, skim it off with a spoon and cook for 3 minutes. When the color of the prawn turns red and the prawn body bends, take it out and the prawn is cooked.
3. Soak in ice water
After the prawns are cooked, don't eat them directly. First, soak them in ice water for a while, and then take them out for eating. Shrimp meat is softer and tender.
You can use cold boiled water without ice water. This is based on the principle of thermal expansion and cold contraction. When hot shrimp meets ice water, it will shrink quickly, become compact and taste better.
How to preserve prawns?
Many people love to eat prawns, and supermarkets often do activities. When they meet them, they will buy some. How to keep them? Frozen directly in the refrigerator? This practice is not desirable, shrimp meat will lose water, and it will not be tender after a while. Let's teach you a simple method. Every family has tools to keep prawns for one year, and they are as delicious as fresh shrimps just bought.
1, fresh shrimps don't need to be cleaned. Prepare some empty pure water bottles and stuff prawns into the bottles, preferably one bottle is the amount you can eat at one time.
2. Fill it with water, tighten it, and put it in the refrigerator for freezing.
Preserved in this way, prawns will not lose water, taste as delicious as fresh shrimps, and will not go bad after a year. They can be cooked after thawing.
