Do Frozen Clams Open When Thawed?

Unless you are a clam connoisseur, you may not know this fun fact about clams! 

It’s true: frozen clams will open easily when they are thawed under warm water.

This is also a sign that your clams are still good. If your clams are already open or dried out before you thaw them, they’re no good.

Why Does it Happen?

Clams are only truly good when they are cooked fresh. Yes, this means alive. Frozen clams are also still alive and fresh since clams freeze in the winter in nature and revive when the water melts.

In your kitchen, the warm water loosens the muscles of the clam meat and causes it to open. This is what should happen and means that your clam is good. If the clam does not open easily, it should be discarded.
