Darne is a French butchery term for a thick cross-section steak cut from a large round fish. The cut is made across the body, usually through the backbone, producing a portion with skin and a central bone. In English, it is commonly called a fish steak.
Large round fish such as salmon, tuna and some cod or hake may be cut into steaks or darnes, depending on the species and fabrication standard. The cut is most useful when the fish is large enough to produce a portion with consistent thickness and shape. A darne is not a boneless fillet portion.
Scale and gut the fish, then cut crosswise into even slices using a sharp knife or suitable fish-cutting tool. Check for loose bone fragments and portion to the required weight. Darnes can be grilled, roasted, pan-seared or gently poached. The central bone helps the portion retain its shape but affects cooking time and portion yield.
Example: grill a salmon darne and serve with lemon, herbs and a light butter sauce, or pan-roast a tuna steak to the required doneness under the operation’s food-safety policy.
A darne is a cross-cut steak from a round fish. A tronçon is a similar crosswise portion from a large flatfish such as turbot. A fillet is a boneless side of fish removed from the backbone.
Chef’s tip: specify the fish species, thickness and weight when ordering. Check for central bones and pin bones, and communicate the presence of bones to guests where relevant.
