Buying Live Shellfish: Practical Steps You Can Use

When buying live shellfish turns out dry or bland, the cause is usually easy to fix. Seafood cooks quickly, so a little preparation goes a long way. Below, we walk through buying live shellfish step by step.

Overcooking

More often than not, live shellfish are best cooked as soon as possible. Mussels and clams generally keep for a day or two in the refrigerator, while oysters can last a bit longer when stored cup side down. Lobsters and crabs should be cooked on the day of purchase. Before cooking, check each shell again and discard any that are open, cracked, or questionable.

Keeping seafood cold right up to cooking time protects both flavor and safety.

A pan that is not hot enough

On a day-to-day level, clams, mussels, oysters, lobsters, and crabs are commonly sold alive, and their freshness depends on keeping them that way until cooking. Knowing what to look for at the market and how to handle them at home makes these shellfish safe and enjoyable.

The practical takeaway is to pull seafood from the heat a moment early, since it keeps cooking on the plate.

Skipping the drying step

Bivalves such as clams, mussels, and oysters should have tightly closed shells or shells that close when tapped. Discard any that remain open or have cracked or broken shells. They should smell like clean seawater, with no strong or unpleasant odor. Heavy shells for their size suggest they still hold their natural liquid.

Moving it too soon

Worth keeping in mind: in the United States, live bivalves are sold with a harvest tag that shows where and when they were harvested. Retailers keep these tags on file for a period of time, and asking to see one is a normal request. The tag offers useful information about origin and freshness.

How to rescue it

Lobsters and crabs should be lively and responsive. A lobster should curl its tail when lifted, and crabs should move their legs and claws. Inactive or limp shellfish may be weak or dead and should be avoided, since they deteriorate quickly once they die.

A better approach

Put simply, transport live shellfish in a cool, ventilated container. The market may provide a bag with ice packed around it, but the shellfish themselves should not sit in melting water. At home, store bivalves in a bowl covered with a damp towel in the refrigerator, never sealed in plastic or immersed in fresh water.

Practical tips

Some practical points to keep in mind:

• Keep seafood in the coldest part of the fridge, ideally on ice.
• Let the pan get properly hot before adding the fish.
• Pat fish dry before it goes in the pan.
• Pull fish off the heat just as it turns opaque.

The bottom line

The best seafood dish is the one you feel confident making again. Keep it simple, watch the cues, and do not rush the prep. That is really all it takes.
