Overview

Atlantic cod (Gadus morhua) is a benthopelagic fish of the family Gadidae, native to the North Atlantic Ocean. It has a mild, flaky white flesh with a low fat content and a clean, slightly sweet flavor. Cod is one of the most commercially important fish in the North Atlantic, historically central to European and North American fisheries.

Origin and history

Atlantic cod has been fished for centuries across the North Atlantic, from the Bay of Biscay to the Barents Sea in the east, and from Cape Hatteras to Greenland in the west [1]. The species supported major European fisheries as early as the medieval period, and Basque fishermen are documented to have crossed the Atlantic in pursuit of cod before Columbus [2]. Overfishing in the late 20th century led to the collapse of the Grand Banks fishery off Newfoundland in the 1990s, a watershed event in fisheries management [3]. Today, cod stocks remain at historically low levels in many regions, with strict quotas in place.

Varieties and aliases

  • Atlantic cod (Gadus morhua) — the primary species sold as cod in the North Atlantic
  • Pacific cod (Gadus macrocephalus) — a separate species, sometimes sold as cod but distinct in range and texture
  • Codling — a term for small or juvenile cod
  • Haberdine — an old English term for salted cod
  • Scrod — a New England term for small cod (or haddock) typically under 2.5 pounds

Culinary uses

Atlantic cod is versatile in preparation due to its firm, flaky texture and mild flavor. It is commonly baked, pan-seared, fried, poached, or grilled. Salted and dried cod (bacalao in Spanish, bacalhau in Portuguese) is a foundational ingredient in cuisines across the Iberian Peninsula, Latin America, and the Caribbean. In the United Kingdom, cod is the traditional fish for fish and chips. In New England, it is used in chowders and fried fish sandwiches. Cod liver is also processed for its oil, a source of vitamins A and D.

Cross-cuisine context

No widely recognized analogue for Atlantic cod exists in Mexican cuisine, as the fish species native to Mexican waters are different. However, dried salted cod (bacalao) is used in Mexican cuisine, particularly in the dish bacalao a la vizcaína, a Christmas Eve specialty in central Mexico. This preparation is a direct descendant of Spanish cod traditions. In other LA-relevant cuisines, cod appears in Japanese cuisine as tara (タラ), often used in nabe (hot pot) dishes, and in Korean cuisine as daegu (대구), used in soups such as daegu-tang.

Notes for cooks

  • Fresh cod fillets should be firm, moist, and have a mild sea-breeze smell. Any strong fishy odor indicates age.
  • Cod flakes easily when cooked. Overcooking will dry it out; cook to an internal temperature of 54°C (130°F) for moist results.
  • Substitutions for cod in recipes include haddock, pollock, or hake, which share similar texture and moisture content.
