As the saying goes, "The autumn wind blows, and the crabs are fragrant." Autumn is a good time to eat crabs, especially the 海游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游戏游� But when we buy, we must also learn to choose.
Some friends choose big crabs, but after they open it, they don’t have much meat, so they waste money in vain. Below I will share with you the old fishermen’s tips for picking sling crabs. The method is simple and practical. Every time the crabs I pick home are fresh, fat and very fragrant!
Tips for choosing
First of all, you must choose live crabs when buying crabs. Although dead crabs are cheap, their taste is very different from live crabs. They are not fresh or fragrant, so we don’t want them no matter how cheap they are.
Second, look at the appearance and color. The color on the back is green and transparent, the color on the abdomen is white, and the lines are dark and black. Such a swift crab is fatter. The darker the lines, the darker the lines, the fatter the swift crab, but the entire abdomen is black, so you can't take it. The navel of the swift crab is protruding and red or yellow in color. Such crab roe (paste) will be very full and taste very fragrant!
Female crabs We eat its crab roe, and male crabs eat its crab paste . As the saying goes, "nine females and ten males", which means that before August and September of the lunar calendar, female crabs are most suitable for eating female crabs. At this time, female crabs are plump than male crabs, but in October, they have to eat male crabs, because in October, the crab paste is the most full and the meat is more delicious and full.
So how to distinguish between male crabs and female crabs? I will teach you a trick: turn the crab over and look at the abdomen. The shell of the male crab abdomen is triangular, and the shell of the female crab abdomen is round.
Third, in addition to looking at the appearance, we also have to pinch the navel and calves of the crab with our hands. If it feels hard to pinch, it means that the crab is very fresh, strong and plump; but if it feels empty when pinched, it means that the crab has been left for a long time and is not very fresh, and the meat will not be too much. The crab roe and crab paste will definitely not be very full, and the umami and fragrance will be much worse.
Fourth, pick up the crab and weigh it. When you weigh it, you will feel the heavier. The fresh and plump crab is the one with a fresh and plump crab. If you can't feel it, you can choose two crabs of similar size to compare. The heavy crabs have more meat, and the yellow or paste is full; on the contrary, the crabs will have less meat, and the yellow or paste will definitely not be full.
When buying crabs, just remember the above 4 points and you can pick fresh and beautiful crabs. Have you learned it as smart?
Note: These places of crab cannot be eaten!
1. Crab cheeks
2. Crab intestine
3. Crab stomach
4. Crab heart
The customary explanation for these "four no-eating" is mostly "cold nature", so it is best not to eat it. In addition, there are safety considerations. For example, crab gills are the respiratory organs of crabs, which are directly in contact with the outside world, and with a large surface area, they are prone to accumulate dirt and heavy metals.
What can’t crabs be matched with? When eating crabs, it is best not to eat cold foods at the same time, nor to drink cold drinks. Crabs are cold in nature. If they are eaten with cold drinks, they will aggravate the stomach cold and may even lead to diarrhea.

☆Die river crabs cannot be eaten!
River crabs are a freshwater product unique to China. The content of free amino acids and nitrogen-containing compounds in their body is relatively loose, which provides favorable conditions for the growth of microorganisms. River crabs all grow in silt, and their living environment is suitable for microbial growth, which leads to a high base of total colonies in and out of fresh river crabs.
Therefore, after the river crab dies, the microbial content increases rapidly, and accidentally eating river crabs may cause food poisoning of Bacillus cereus and Vibrio parahaemolyticus.
Dead crab, even if it is just dead, don’t eat it.
☆Sea crab Can't eat
Sea crabs grow in special environment and are very likely to die if they are salvaged. However, the salt content in the sea water is high, and there are fewer bacteria inside and outside the crabs. Therefore, dead sea crabs are frozen in time and well-preserved intact are edible, but they cannot be stored for too long.
