live littleneck or mahogany clams

Littleneck clams (Mercenaria mercenaria) and mahogany clams (Artica islandica) are bivalve mollusks found in Atlantic coastal waters, prized for their firm meat and sweet flavor. Littleneck clams, native to the eastern coast of North America, are medium-sized hardshell clams typically 1.5 to 2 inches across with smooth, dark shells often displaying radiating grooves. Mahogany clams, also called ocean quahogs, are larger, older specimens of the same species or related species, with darker, mahogany-colored shells and denser meat that benefits from longer, slower cooking. Both varieties have a briny, subtly sweet flavor profile and firm, slightly chewy texture when properly cooked. The terms "littleneck," "cherrystone," and "quahog" refer to size grades within the Mercenaria mercenaria species.

Littleneck and mahogany clams are consumed raw on the half-shell, steamed, roasted, or incorporated into chowders, pastas, and seafood stews. Raw littlenecks are served chilled with cocktail sauce or mignonette as an appetizer, while their firm meat makes them ideal for clam bakes and traditional New England chowders. Mahogany clams, with their denser meat and stronger brine, are better suited to longer cooking methods such as slow steaming or stewing, where their pronounced flavor can stand up to robust broth bases and aromatic vegetables. Both varieties pair well with white wine, garlic, parsley, and butter-based preparations. In Italian cuisine, littlenecks feature prominently in pasta alle vongole (clams with pasta).
