Frequently Asked Questions About Clam

How do you purge sand from clams?

Soak live clams in cold, salted water in the refrigerator, then scrub their shells under running water. Don’t use fresh water for soaking: clams may open and take it in, and the salt helps them release grit.

How do you cook clams?

Steam clams or cook them in a covered pan with a little liquid until their shells open. Remove them as they open to keep the meat tender, and discard any that remain closed after cooking.

Are clams safe to eat raw?

Raw clams can carry harmful bacteria and viruses, so eating them is riskier than eating them cooked. Lemon juice does not make raw clams safe; cook them thoroughly, especially if you are pregnant or have a weakened immune system.

How can you tell if clams are fresh?

Fresh live clams smell clean and briny, not sour or strongly fishy. Their shells should be closed, or close when tapped; discard clams with broken shells or ones that stay open when handled.

Why do some clams stay closed after cooking?

A clam that stays closed after cooking may not have been alive and healthy before it went into the pan. Discard it rather than trying to pry it open, since you cannot confirm it is safe to eat.

How should you store live clams in the refrigerator?

Keep live clams in an open or breathable container in the refrigerator, covered with a damp cloth. Don’t store them submerged in water or sealed in an airtight bag, and check that they are alive before cooking.

Can you freeze clams?

Yes, you can freeze clam meat in an airtight container. Thaw it in the refrigerator and cook it promptly; freezing can affect the texture, and thawed clams should not be refrozen.

What is the difference between clams and mussels?

Clams and mussels are different kinds of bivalve shellfish. Clam shells are generally more rounded, while mussels often have elongated, dark shells; they also differ in flavor and how they are commonly prepared.

Do clams need to be soaked before cooking?

Soaking clams in cold, salted water can help them release sand, but it is not a substitute for scrubbing the shells. Keep them chilled while soaking, then rinse them before cooking.

Can you eat clams that are slightly open before cooking?

Only if the clam closes when you tap it or handle it; that response suggests it is still alive. If it stays open, discard it rather than cooking it.

What is Clam?

Clams are bivalve shellfish that live buried in sandy or muddy coastal beds. The name covers many species harvested around the world, and their size and flavour vary by region. The tender meat is usually cooked in the shell until it opens, then eaten on its own or added to other dishes.

Clams taste gently briny, and brief cooking keeps them tender. They appear in New England chowders, Italian pasta dishes and many coastal cuisines; wherever you live, serve them simply steamed with lemon or fold them into pasta, rice or soup. They provide plenty of protein along with vitamin B12, iron and selenium, while being naturally low in fat. A side of greens and a lighter broth make a balanced meal.
