While testing the Braised Red Snapper Puttanesca recipe, we occasionally couldn’t find snapper fillets, but we could find whole snappers. No problem—filleting a snapper (or any other similar fish) is easy if you follow these steps. Just be sure to use your sharpest knife, whether it’s a fillet knife or a chef’s knife.
A note on fish scales: Before you fillet a whole fish, it should be scaled. Doing the job yourself isn’t difficult, but it’s messy, because the scales tend to fly all over and you find them in weird places around the kitchen for days after. For this reason, we always ask the fish monger to do the scaling for us. And actually, a good fish monger will also fillet the fish for you, but where’s the fun in that?
Filleting a Whole Fish
Skinning is optional
Put the fillet, skin side down, on the cutting board. Starting at the tail end and holding the knife parallel to the cutting board, slice between the flesh and the skin, as close to the skin as possible, until you can grasp the tail end of the skin with a paper towel. With the knife angled ever so slightly down toward the skin, slice along the skin, using a gentle sawing motion. As you slice, simultaneously pull on the tail skin in the opposite direction to maintain pressure on the cutting edge of the knife. If you miss a spot, trim it away.
