Haddock fillets are cuts of fish taken from the haddock, a popular species found in the North Atlantic Ocean. Known for their mild flavor and flaky texture, these fillets are often used in various culinary dishes, including fish and chips. They are a good source of protein and contain essential nutrients like omega-3 fatty acids. Haddock is typically harvested through commercial fishing methods, and it is often sold fresh, frozen, or smoked. When cooking, haddock fillets can be baked, grilled, or pan-fried, making them a versatile ingredient in many recipes.
