cod/haddock/monkfish fillets
All three are excellent sources of lean protein and B vitamins, particularly niacin and B12. They contain beneficial omega-3 fatty acids, though in lower quantities than oily fish, and are low in calories and fat.
About
Cod (Gadus morhua), haddock (Melanogrammus aeglefinus), and monkfish (Lophius piscatorius) are three commercially important white fish species found in North Atlantic waters. Cod is a large gadiform fish with white, flaky flesh, mild flavor, and a firm texture that holds together well during cooking. Haddock, a smaller relative of cod, has slightly sweeter, more delicate flesh with a finer texture and contains a distinctive dark lateral line. Monkfish, despite its grotesque appearance with a large head and small tail, yields firm, lean white flesh often compared to lobster for its dense, slightly sweet character. All three are typically sold as fillets—boneless cuts from the body—and are valued for their versatility, neutral flavor, and ability to absorb accompanying sauces and seasonings. These species have been staples of North Atlantic fisheries for centuries, particularly in British, Scandinavian, and Mediterranean cuisines.
Culinary Uses
Cod and haddock fillets are foundational in British fish and chips, where they are battered and deep-fried, and appear in Spanish bacalao dishes where salt-cured forms are reconstituted and braised. Haddock is traditional in Scottish smoked haddock preparations and British kedgeree. Monkfish fillets, prized for their firm texture, are used in Mediterranean bouillabaisse, grilled with olive oil and herbs, or pan-seared and served with rich sauces. All three fillets are excellent for poaching, steaming, baking en papillote, or shallow frying. Their mild flavor makes them suitable for delicate preparations with white wine, butter, and herbs, or more assertive treatments with spices and bold seasonings. The fillets are often paired with lemon, capers, mustard, and tomato-based sauces.
