Intermediate Butchery and seafood

Shucking oysters is opening a live oyster with an oyster knife, cutting it free, and keeping its juice in the cup.

How do you do it?

1. Scrub the shell. Fold a thick towel over your holding hand or wear a cut-resistant glove, and set the oyster cup side down on a board.
2. Wedge a short, blunt oyster knife into the hinge and twist, like turning a key, until it pops. Keep your hand behind the hinge, never ahead of the tip.
3. Slide the blade along the inside of the top shell to cut the muscle, then lift the top off.
4. Run the knife under the oyster to free it, keeping the shell level to save the juice.

Why does it work?

An oyster is held shut by one strong adductor muscle; cutting it is what lets the shell open. Oysters must be alive when you open them: their flesh spoils fast after death and you can't know how long a dead one has been sitting. Raw oysters can carry Vibrio bacteria; people with liver disease, weakened immunity or pregnancy should eat them cooked.

What are the common mistakes?

• Using a paring knife — the thin blade snaps or slips into your palm.
• Prying at the side — the shell shatters into grit.
• Keeping an oyster that's open and won't close, or smells bad — toss it.
