Whole Fish Scoring for Steaming / Frying

Applied to medium whole round fish kept intact: sea bass, branzino, red snapper, tilapia, grouper, carp, and whole mackerel. Also applied to large flat fish grilled bone-in (turbot, flounder). The scores penetrate the lateral muscle — the main eating flesh — between the dorsal and ventral fin lines.

1. 1Scale the fish and clean the cavity; remove gills if steaming (gills impart bitterness). Pat the skin completely dry — wet skin leads to oil spatter when frying and prevents clean cuts.
2. 2FOR STEAMING (diagonal single cut, Cantonese method): Hold the fish on its side. Make 3–5 cuts at 45 degrees to the spine, beginning just behind the head and spaced 3 cm apart, cutting 1–1.5 cm deep. Do not cut all the way to the backbone. Repeat on the other side. Lay the fish on sliced ginger in the steaming dish; steam over high heat for 8–12 minutes (for a 600 g fish) until the flesh at the deepest score point pulls away from the bone with a chopstick.
3. 3FOR DEEP-FRYING (cross-hatch, Cantonese 'squirrel fish' style): After diagonal scoring one direction, make a second set of cuts in the opposite direction (forming diamonds). This allows each diamond of flesh to fan open in the hot oil, creating the characteristic chrysanthemum texture. Dust with potato starch before frying at 180 °C.
4. 4FOR SICHUAN BRAISING (fry then braise): Score diagonally, deep-fry the whole fish until golden, then transfer to a wok of doubanjiang-based braising sauce, spooning sauce over the scores repeatedly to penetrate.
5. 5Rub the scored surfaces with the seasoning or marinade immediately before cooking — salt will draw moisture if applied early, softening the skin.
6. 6At service for a steamed fish, pour boiling hot oil down the length of the scores after the soy-ginger dressing is added — the sizzle blooms aromatics deep into the cuts.

• Dry the skin meticulously before scoring — damp skin drags the blade and produces ragged, torn cuts rather than clean incisions.
• Use a thin, sharp boning or Chinese cleaver tip; a serrated knife is useless here.
• Score at 45 degrees — cuts perpendicular to the spine sever muscle fibre cleanly but may cause the fish to crack apart at the scores during cooking; angled cuts stay intact.
• Depth calibration: your knife should glide until you feel the lightest resistance of the rib bones or backbone — stop just before contact.
• For symmetrical presentation, score both sides with the same number and angle of cuts, starting from the same reference point.

• Scoring with a mandoline blade (butcher's tip)

  A box cutter blade run along a ruler produces perfect-depth parallel scores on thin-skinned fish like sea bass

• Skewer holes (alternative for steaming)

  For delicate fish that may break: insert bamboo skewers through the cavity to prop open and promote airflow instead of deep scoring

• Fillet sections instead of whole fish

  When timing control is paramount, fabricating into fillets and steaming on a bed of aromatics eliminates the uneven-thickness problem entirely at the cost of presentation

• Whole Fish — Backbone Removal for Grilling (Spatchcock Fish)

  An alternative approach: removes the problem of uneven thickness entirely by opening the fish flat

• Butterfly Fillet (Herring / Sardine Method)

  Full deboning of small fish — scoring is the lighter version for fish too large to butterfly conveniently

• Darne

  Slicing the fish into bone-in steaks is another solution to the cooking-time-gradient problem
