-lb. pieces fillet such as haddock

Haddock (Melanogrammus aeglefinus) is a gadiform saltwater fish found in the North Atlantic, commonly harvested from the waters off Iceland, Norway, and the northeastern United States. This demersal species exhibits a distinctive coloration with a dark grey-brown back, silvery sides, and a characteristic dark lateral line. The flesh is white, flaky, and mild-flavored with a delicate sweetness, making it highly prized for culinary applications. Haddock fillets are boneless cuts of fish muscle that provide excellent texture and cook quickly, distinguishing them from whole fish or steaks.

Haddock fillets are versatile in both traditional and contemporary cooking. They are foundational to British and Scandinavian cuisines, particularly in fish and chips preparations where they are battered and deep-fried until golden. The mild flavor suits poaching in court-bouillon, steaming en papillote, and pan-searing with butter and lemon. Haddock readily accepts diverse preparations including grilling, baking, smoking (traditionally in Scottish cuisine), and incorporation into fish soups and stews. The flaky texture makes it suitable for flaking into fish cakes, paté, and composed dishes paired with light sauces.
