Shellfish Smarts

Buying Shellfish

Purchase fresh, live mollusks with shells that are tightly closed—opened shells can indicate mollusks that are already dead and starting to spoil. Select the most sustainable choices by using Monterey Bay Aquarium’s free Seafood Watch app (seafoodwatch.org)

Prepping Shellfish

Shellfish are filter feeders and easily pick up sand and tiny gravel from their marine environment. To remove particulate matter, soak shellfish in saltwater (about 3 parts cold water to 1 part salt)—it needs to be salted to keep them alive while prepping.

Cooking Shellfish

People commonly overcook mollusks, which results in a rubbery texture. To keep them tender and plump, cook only until they open.

Eating Bad Shellfish

To check for freshness, take a quick sniff. If the mollusk smells like the sea, you’re in the clear. But if it smells the least bit unpleasant, it’s likely beginning to decay, so toss the entire batch.
