lb. cod or haddock fillets

Cod and haddock are closely related gadiform fish (family Gadidae) native to the North Atlantic and Arctic waters. Cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) are distinguished by their body structure—haddock possess a distinctive dark lateral line and a dark blotch above the pectoral fin, while cod lack these markings and have a more robust build. Both species have white, flaky flesh with a mild, slightly sweet flavor and firm texture when fresh. The fillets, when trimmed of skin and bones, are lean, delicate, and versatile in the kitchen. Haddock typically has a more subtle flavor than cod, while cod offers slightly firmer flesh.

Historically, both species have been staples of North Atlantic fisheries for centuries, with extensive commercial and artisanal harvests supporting European and North American cuisines.

Cod and haddock fillets are fundamental ingredients in numerous traditional preparations across European cuisines. They are commonly pan-fried, baked, poached, or steamed, with applications ranging from British fish and chips to French sole meunière-style preparations and Scandinavian gravlax variations. The mild flavor and tender, flaky texture pair well with acidic elements (lemon, vinegar), delicate fats (butter, olive oil), and aromatic vegetables. Both are essential to New England chowders, Mediterranean fish stews, and Portuguese bacalhoada (salt cod). Their neutral flavor profile makes them suitable for both simple preparations and complex sauce accompaniments, and they accept smoking and salting for preservation.
