Darnes (Cross-Cut Fish Steak)

Cut from the thicker mid-section of any large round fish — salmon (the most classic darne), cod, tuna, swordfish, striped bass, mahi-mahi, or large trout. The head, collar, and tail taper are typically excluded. Each fish yields 4–8 darnes depending on desired thickness (2.5–4 cm is standard).

1. 1Dry the darne well and season generously — the large bone mass absorbs heat and requires slightly longer cooking than an equivalent boneless portion.
2. 2For grilling: oil the grate and the steak; cook over direct medium-high heat 3–4 minutes per flat face, then 1 minute on each curved skin edge if thickness allows. Resist moving the steak to allow grill marks to set.
3. 3For pan-searing: start in a hot, oiled pan on the flat cut faces; finish in a 200°C oven for 5–8 minutes for a 3 cm steak.
4. 4For poaching: simmer in seasoned court-bouillon at 75–80°C; allow 8–10 minutes per 2.5 cm of thickness. The bones signal doneness — flesh releases cleanly from the spine when properly cooked.
5. 5Rest 2–3 minutes before serving; internal temperature should reach 52–55°C for salmon, 58–62°C for cod.
6. 6To eat: diners separate the two lobes from the central spine at the table; provide a small fork or fish knife.

• Use a sharp, heavy chef's knife or a fish scimitar; the goal is to cut through the spine in one or two clean strokes, not saw through it repeatedly (which frays the flesh).
• Dress the fish first (remove gills, gut, and rinse the cavity); scales may be left on or removed depending on whether you plan to serve the skin.
• Mark the fish at regular intervals (2.5–4 cm) before cutting; use a ruler for restaurant consistency.
• Remove pin bones before serving if present by running pliers along the lateral line after cutting — some cooks prefer to remove them before cutting, which is more difficult but cleaner.
• For presentation-grade work, trim ragged belly skin with scissors after cutting.

• Fish Suprême

  Boneless bias-cut portion — faster to cook, no bone-navigation at table, but lacks the structural cooking advantages and rusticity of the darne.

• Pavé (fish)

  Thick square boneless cut — similar thickness but fully boneless; more refined, less character.

• Tronçon

  The flat-fish equivalent — bone-in cross-cut from turbot or brill; same concept, different fish geometry.

• Tronçon

  Flat-fish cross-cut steak — the darne's flat-fish counterpart.

• Fish Suprême

  Boneless bias-cut portion — the refined alternative to the darne's rustic bone-in format.

• Fish Fillet vs. Darne vs. Pavé

  The French classification that defines darne as the bone-in steak category.
