Selection tips for oysters

1, look at the oyster's shell is tightly closed

Normally, the oyster's shell should be closed and intact, if the oyster's shell is open, the oyster is definitely not fresh. We try to pick the oysters with closed shells when we buy them, and we should see whether they are tightly closed in the end, if there is a small slit, gently break the shell is certainly not to be bought, such oysters are most likely to have been hung up, and there is no reaction to touch. We touch the gap in the shell, if it will close on its own, it means that the oyster is still alive, you can buy.

2, look at the shape of the oyster

In the selection of fat oysters, the first thing is certainly to look at the head first. The head is certainly a little larger more cost-effective, and secondly, the shell of the oyster is divided into two sides, there is meat on the back of the shell side should be raised, the higher the raised represents the meat more and more fat. And if the oyster itself is not big, the bump is also relatively small basically flat, this oyster is not recommended to buy, basically nothing meat, completely buy is a shell, pure waste of money.
