What are oysters, how to eat them, and what are oysters?

After eating seafood for so many years, I finally know the difference between oysters and oysters, so don't buy blindly in the future.

As a member of coastal city life, I grew up eating seafood. But after eating seafood for decades, I always thought that oysters and oysters were the same ingredients, but the names were different, until an elder told me not long ago that oysters and oysters are very different in appearance, taste and nutritional value.

They all belong to the seafood shellfish category, some places have been calling oysters oysters, but oysters are actually just a variety of oysters, due to the similar appearance and taste, if you are not an insider, you can't distinguish their differences, today we will learn how to distinguish oysters from oysters, next time you go to the seafood market don't buy the wrong waste of money.

The appearance is not the same.

Oysters and oysters are shellfish molluscs, oysters are larger in size and size, one can even weigh up to 1 catty, because the oyster cultivation time is too long, it takes about 2-3 years, so its production is less, ** more expensive. And the oysters have two shells, one is large but convex like a triangle, the other is small but very flat, and the overall appearance is uneven, so the appearance is a little rough to the touch, the oyster breeding period is very short, and the reproductive ability is strong, so the number is relatively large, and it can be produced and marketed in less than a year, which is cheaper.

The growing environment is different.

Oysters do not have high requirements for the temperature and environment of the seawater, so they can be found in most marine areas. Oysters like cold seawater, so when cultivating in captivity, we must choose a shallow bay with half fresh water and half seawater, or at the confluence of the sea and rivers.

The nutritional value is not the same.

Although oysters also belong to the oyster category, their nutritional value greatly exceeds that of oysters, such as the zinc content of trace elements required by the human body, 100 grams of oyster zinc content is as high as milligrams, while 100 grams of oyster zinc content is only milligrams, a difference of several times. In addition to zinc, oysters also have more protein than oysters, so why oysters are called "seafood milk", which is why oysters are so expensive.

It's not the same.

Whether it is oysters or oysters, they are delicious food on our table, but there are differences in the method, oysters are usually eaten directly by dipping some sauce and eating them raw, the meat is tender and juicy, or steamed and grilled with garlic. In addition to being used as a delicacy, oysters can also be made into oyster sauce.

Finally, when choosing oysters and oysters, everyone should choose a high degree of freshness, if you eat stale oysters or oysters, it is easy to cause diarrhea and other adverse reactions. To determine whether oysters and oysters are fresh or not, teach you a simple way to pick those that will close quickly when you touch them. Do you like to eat oysters and oysters?
