🧰 Required Tools & Equipment
- ✓ Flexible fillet knife (7-9 inch)
- ✓ Sturdy cutting board (large)
- ✓ Fish scaling tool or dull butter knife
- ✓ Fish bone tweezers or clean needle-nose pliers
- ✓ Cut-resistant glove
📦 Materials & Supplies
- ✓ Whole fresh salmon
- ✓ Paper towels
- ✓ Cold running water
- ✓ Crushed ice tray or platter
⚠️ Safety Checkpoints & Warnings
- • Wear a cut-resistant glove on the non-dominant stabilizing hand at all times.
- • Always direct the cutting edge away from your body and free hand.
- • Keep the cutting board stabilized with a damp cloth underneath to prevent sliding.
📋 Step-by-Step Guide (6 Steps)
Scale and Rinse the Salmon
Place the salmon flat on the cutting board. Scrape from the tail toward the head using short, firm strokes with a scaler or the back of a knife to remove loose scales. Rinse the fish with cold water and pat completely dry with paper towels to improve knife grip.
- • Skin surface appears smooth and matte with no loose, shiny scale clusters.
- • Fish skin is dry to the touch with no excess surface slime.
- • Scaling toward the tail instead of against the grain toward the head.
- • Leaving the skin wet, making the fish slick and dangerous to hold.
Open the Belly and Eviscerate
Insert only the tip of the fillet knife into the vent near the tail. Slice shallowly along the centerline up to the base of the gills, taking care not to puncture the intestines. Reach in with your fingers and pull out all internal organs in one smooth motion.
- • A continuous straight slit running from the vent to the throat.
- • Abdominal cavity is empty with the dark bloodline along the spine exposed.
- • Inserting the knife too deep and slicing into the stomach or gall bladder.
- • Tearing the delicate belly meat while pulling the viscera.
Make the Pectoral Collar Cut
Lift the pectoral fin and angle your knife blade at 45 degrees toward the head. Cut down through the flesh until the blade contacts the spine, without cutting through the backbone itself. Flip the fish and repeat the exact angle on the opposite side.
- • Angled diagonal cuts behind the gills on both sides meeting at the top of the head.
- • Knife edge resting against the central spine bone without severing it.
- • Cutting straight down at 90 degrees, leaving valuable neck meat on the head.
- • Severing the spine entirely before filleting the sides.
Remove the Top Fillet
Turn the knife flat against the backbone at the head cut. Using smooth, full-length slicing strokes, glide the blade along the top of the ribs down toward the tail, letting the spine guide the flat of your knife. Separate the entire top fillet from the frame.
- • One full, clean fillet lying skin-down with smooth meat surface.
- • Exposed backbone on the frame with minimal pink flesh remaining on the ribs.
- • Sawing back and forth aggressively, causing ragged meat edges.
- • Angling the blade upward and cutting through the fillet meat prematurely.
Remove the Bottom Fillet
Flip the remaining frame over or keep the carcass stationary and insert the knife just above the backbone at the tail. Slice forward along the spine toward the head collar, lifting the frame slightly with your free hand to maintain clear visibility of the bone structure.
- • Second intact fillet freed cleanly from the frame.
- • Clean, translucent rib cage structure visible with negligible meat residue.
- • Lifting the spine too aggressively, bending the spine and forcing the knife into the meat.
- • Losing the line of the backbone near the tail section.
Trim Rib Bones and Pin Bones
Lay each fillet skin-down. Slide your knife just under the thin rib cage membrane and slice forward to shave the rib bones off in one thin sheet. Run your fingertips down the centerline to locate pin bones, then extract each one cleanly in the direction the bone points using tweezers.
- • Belly flap is smooth and completely free of rib bones.
- • Centerline of the fillet is completely smooth with zero protruding pin bone tips felt.
- • Pulling pin bones straight up or backward, tearing the delicate fillet flesh.
- • Shaving off too much belly meat when removing the rib cage.
