How to tell whether crabs are good or bad?

First of all, hairy crabs must be eaten alive, and the dead ones can't be poisonous. Please remember that it's not advisable to drink beer when eating crabs, which is not good for your health. It's better to drink white wine or red wine. You can't eat persimmons together when eating crabs.

Now, to formally answer your question, the "green shell and white belly, golden claws and yellow hair" mentioned upstairs is a unique physical feature of high-quality Yangcheng Lake hairy crabs, not all of them have it, but only ordinary hairy crabs. It's good to have a uniform body color. But crabs with high crawling speed are generally in good health, and crabs with good health are generally good in taste. On the basis of physical fitness, let's pick the best. According to the seasons, in August and September of the lunar calendar, it is time to eat female crabs (the navel is round, the big claws are small, and the claws are few), and in October of the lunar calendar, it is time to eat male crabs (the navel is an isosceles triangle, the big claws are thick, and the claws are few) The female crab begins to enter the reproductive preparation period in August/September of the lunar calendar, and the male crab enters the reproductive preparation period in October of the lunar calendar. During these two periods, the endocrine of the crab is improved, so the crab paste is thick, the female crab is yellow (orange after cooking) and the male crab is paste (white, gelatinous and translucent after cooking). Let's talk about how to pick crabs. In fact, it is very simple to pick crabs. Pinch the smallest joint of the crab with your hands, the harder the better. Generally, there is no meat and yellow paste after cooking.

There are many ways to cook crabs, such as frying and frying, and soup, but the most classic and simplest way is cooking. The way to do this is to wash the crabs, mainly where there is a lot of dirt in the chelated parts, and turn over the navel of the crabs, and squeeze out the excrement that has not been discharged by hand. Pay attention to safety when turning over the navel, and don't be caught by the crabs. After washing, directly put them into the pot for cooking. When boiling crabs, boil them for 7 minutes after boiling, 8 minutes after boiling in 3-2 to 4-2 rooms, and 8-9 minutes after boiling in 4-2 rooms. Generally, the time will increase by about 1 minute for each weight gain of crabs, and 15 minutes for steamed crabs after boiling in 3-2 to 4-2 rooms, and 2 minutes for each weight gain of crabs. It is not easy to kill and destroy the toxicity and parasites if the time is not enough, but if the time is too long, the crab will lose its delicious taste, and it is not easy to separate the meat from the shell, so it is inconvenient to eat.

I will tell you some tips for buying crabs. When buying crabs, buy dried crabs, that is, if the merchants don't keep crabs in water, the weight of crabs kept in water will increase by about 2%, and the crabs are only a catty, but the water is only a catty. It is best to buy crabs in the aquatic market. The same crab supermarket is more than 2% more expensive than the aquatic product market.

I am used to buying crabs the day before eating crabs and keeping them in water for one day after I come back, so that when I eat them, it tastes good and it is convenient to clean them. Just rinse them with water, but it requires equipment, otherwise crabs will easily die at home.

Crabs used to be found only in some areas, but now the breeding technology has made crabs cultured in many parts of the country, although crab seedlings are used. However, the taste of crabs in different breeding environments is completely different. Jiangsu crabs are the best, especially Yangcheng Lake and Taihu Lake crabs. The farther north you go, the more you don't have to eat Northeast crabs (there are hairy crabs in Northeast China now).

That's all I can tell you, I hope it's useful for you. If you think my answer is good, can you get more points?

Have a good time eating crabs.
