Overview

The blue mussel (Mytilus edulis) is a medium-sized edible marine bivalve mollusc in the family Mytilidae. It is native to the North Atlantic and is one of the most widely farmed and harvested mussel species globally. The meat is tender, briny, and slightly sweet, with a firm texture when cooked.

Origin and history

Blue mussels are native to the temperate waters of the North Atlantic, ranging from the Arctic coast of Europe and North America south to the Mediterranean and the Carolinas. They have been harvested by coastal peoples for thousands of years; shell middens in Europe and North America attest to their prehistoric importance. Commercial aquaculture of Mytilus edulis began in Europe in the 13th century, with French bouchot culture (pole-grown mussels) documented as early as the 1200s [1]. Today, the species is farmed extensively in Spain, France, the Netherlands, Canada, and the northeastern United States.

Varieties and aliases

  • Common names: blue mussel, edible mussel, bay mussel (in some regions)
  • In French: moule commune
  • In Spanish: mejillón común
  • In Italian: cozza comune
  • In Dutch: mossel
  • In German: Miesmuschel
  • In Norwegian: blåskjell
  • In Japanese: ムラサキイガイ (murasaki igai, though this name is also used for Mytilus galloprovincialis in some contexts)

Culinary uses

Blue mussels are typically steamed, boiled, or baked in their shells. They are commonly cooked in a broth of white wine, garlic, shallots, and herbs (moules marinières in French cuisine). In Belgian and French cooking, they are served with fries (moules-frites). In Spanish cuisine, they appear in escabeche, paella, and as tinned conservas. In Italian cooking, they are used in spaghetti alle vongole (substituted for clams) or in zuppa di cozze. The meat is also smoked, pickled, or added to chowders and stews. Common pairings include lemon, parsley, garlic, butter, white wine, and cream.

Cross-cuisine context

Blue mussels have no direct analogue in traditional Mexican cuisine, as the North Atlantic species is not native to Mexican waters. However, the Pacific coast of Mexico is home to related species such as the choro (Mytella strigata) and the mejillón (Modiolus capax), which are prepared similarly: steamed with epazote, garlic, and chiles, or added to caldos and arroz a la tumbada. In the broader LA-relevant corpus, blue mussels are closest to the mejillón used in Peruvian and Spanish-influenced Latin cooking. In East Asian cuisines, mussels (hong hap in Korean, murasaki igai in Japanese) are often steamed with ginger and scallions, or used in spicy stews such as Korean haejangguk or Japanese miso soup.

Notes for cooks

  • Live mussels should be tightly closed or close when tapped. Discard any that remain open or have cracked shells.
  • Store in a bowl covered with a damp cloth in the refrigerator, not in sealed plastic or submerged in fresh water. Use within 24 to 48 hours.
  • The beard (byssal threads) should be removed just before cooking. Do not debeard until ready to cook, as the mussel may die.
