How to Open and Serve Oysters

This is one of the kitchen tasks most likely to cause hand cuts, so take precautions before you begin. Do not hold an oyster with a bare hand; wrap it in a thick, folded kitchen towel or wear a cut-resistant glove. The tool should not be an ordinary kitchen knife: an oyster knife is short, thick, and blunt-tipped because its job is to pry, not slice. A thin-bladed knife can break under this pressure, sending the broken tip into your hand.

The two shells meet at one end; the narrow, pointed end is the hinge and the opening point. Place the oyster in the towel with the flat shell on top and the cupped shell underneath so its liquid does not spill. Insert the knife tip a few millimeters into the hinge and twist without pressing down. At the right spot, the lock releases with a light click. If you hear no click, you are in the wrong spot; do not force the knife. Remove it, shift it by 1 or 2 millimeters, and try again.

Once the lock releases, slide the knife inward from the hinge and move it along the inside of the top shell. The goal is to cut the muscle attaching the oyster to the top shell; if the blade angles downward, it cuts the oyster meat and spoils its appearance. Once the muscle is cut, lift off the top shell. Then use the same knife to cut the muscle at the bottom shell so the meat is released but stays in place. Pick out any shell fragments one by one with the tip of the knife.

Inspect each opened oyster immediately. Its liquid should be clear, not cloudy or milky; the meat should look plump, glossy, and moist. Discard an oyster that is shrunken, dried out, stuck to the shell, or has a strong odor. If an oyster arrives with its shell already open and does not close when tapped lightly, it is not alive; do not open it and discard it. Check every oyster individually rather than judging the whole batch together. Do not pour out the liquid inside the shell; it is part of the oyster’s own flavor and is served with it.

Serve oysters immediately after opening; do not let them sit. Do not put ice on top: melting ice gets into the oyster and dilutes its flavor. Line a serving plate with coarse salt, crushed ice, or seaweed and nestle the oysters on top so the shells do not tip over and spill their liquid. Serve with a lemon wedge. If eating oysters raw, know where they came from; an oyster whose safety has not been documented must not be eaten raw and should be cooked instead. Cooking time for oysters is very short: remove them from the oven or grill as soon as the edges curl; cooking them longer makes them rubbery.
