How to fillet a Redfish?
Once you’ve found the perfect redfish filleting knife, the whole filleting task becomes easy and efficient for you. Below, we have outlined for you the key steps for filleting a redfish the right way.
Step 1. Make the first cut on the redfish behind its gill flap and near the pectoral fin. Then, position your knife up and under the scales (this angle will ensure you don’t cut through them) and cut downward until you hit the fish spine.
Step 2. Use the tip of your knife to make a cut towards the tail and just above the dorsal fins. Make sure you don’t go too deep with this cut. A cut of just an inch or so of the fish meat is recommended.
Step 3. Make another cut to the tail of the redfish and finish by cutting the connection between the fish and the fillet.
Step 4. Using the tip of your fillet knife, cut the meat away from bones. use the bones as your guide and make a little cut at a time for the best results. Lifting the meat upward will help expose the uncut connection.
Step 5. On reaching the center (this is essentially where the spine is located), cut up and over it whole ensuring you back down to maximize the amount of meat you get off the spine.
Step 6. Cut along the ribs down the fish belly to remove the entire fillet from one side of the fish.
Step 7. Now that you have a fillet set apart, flip your fish to the other side and repeat the above filleting process for the uncut side.
Step 8. Lastly, you should remove the skin from the fillets. To do so, hold the tail end of your ready fillets and start cutting forward as you hold your knife at a shallow angle of around 30 degrees outward. Make back and forth cutting motions while holding the skin to make the skinning part easy for you.
