Clam is a general culinary name for several edible bivalve molluscs. Varieties range from small, tender clams to large species used for chowder or other preparations. Species and market names differ by region; in British Columbia and the Pacific Northwest, Manila clams, littlenecks, geoduck and razor clams are among the familiar types. The French word palourde refers to certain clams, depending on species and region.
Clams may be steamed, grilled, baked, chopped for chowder or added to pasta and seafood stews. Many small clams cook quickly; remove them from the heat as soon as they are cooked to avoid a rubbery texture. Species differ in how they open during cooking, so follow the supplier’s guidance rather than relying on shell opening alone as a safety test.
Example: steam Manila clams with white wine, garlic and parsley, or use chopped quahogs in clam chowder.
Purchase shellfish from approved sources with required harvest and traceability information. Keep live clams under the supplier’s specified refrigerated conditions, protect them from contamination and follow local shellfish advisories. Raw shellfish can carry pathogens and are not risk-free even when properly sourced.
Chef’s tip: confirm species, size, harvest area and whether the product is live, shucked or cooked before planning a recipe. The species and product form affect yield, portion cost and cooking time.
Allergen note: clams are molluscan shellfish and must be identified clearly and managed as an allergen.
