2. The correct way to eat crabs
Many people say they like crabs, but they don't. They tend to chew, or simply eat crab roe and throw away the crab legs. Some gourmets say that people who can't eat crabs usually bite them with shells and meat, chew them a few times, and spit them out with shells and meat, so that the crabs that can really be eaten in their stomachs are very limited. Some readers said in an interview that when eating crabs, you should first open the crab shell, suck out the crab paste, then divide the crab body into two parts, eat one side and then eat the other side, and finally eat crab claws and claws. According to the analysis of gourmets, these people don't know how to eat crabs and can't really appreciate the delicacy of crabs.
It is understood that the correct way to eat crabs is to remove the round cover on the crabs first. If it's a female, you'll see crab roe from Huang Chengcheng, which is the best thing on crabs. There are some white things like bristles near the thighs on both sides of the crab, so you can't eat them. After eating crab roe, you can eat crab meat, which is as white as fish.
It's best to break it in half when eating crabs, so as to reveal the shiny crab meat. Now, when some hotels make crabs, they directly break the crabs in half, so that crab roe and crab meat are directly exposed to the foodies. Crab legs are usually eaten last, because it takes time to eat crab legs, and there is not much meat inside. Of course, when eating crabs, try to finish your legs, not only because the meat inside the legs is delicious, but also to avoid waste.
Warm reminder: Although crab meat is nutritious, it has high cholesterol content. If you add crab roe and crab paste, it will be even more impressive. Therefore, people who have concerns in this area (such as gallstones, systemic lupus erythematosus, people with allergies and gastrointestinal discomfort) can exercise restraint when eating, so as not to affect their health.
