How to Fillet a Flatfish

Remove the head and viscera of the fish (usually your fishmonger does this). 1. Starting with the dark side up, use a long flexible filleting knife and cut down the center of the fish to the bone. 2. Using the tip of the knife, remove the fillet from the backbone right to the edge of the fish with long sweeping strokes. Repeat on the second half of the dark side. 3. Turn the fish over and remove the two fillets and the white side in the same way.
