Removing the skin from salmon can be a bit tricky, but this trick makes it a lot easier. Place the salmon fillet on a cutting board skin side down and insert a sharp knife (a chef's knife works fine) right above where the skin connects to the pink fillet. Cut along the skin and push with your knife away from you with one hand while pulling the cut salmon skin towards you with the other. This push and pull movement makes a nice clean cut and removes the skin well. Once you have the skin removed look at the fillet and if some of the brownish/gray bloodline still remains you can clean it up with your knife.
