Albumin is a protein that is pushed out of the muscle fibers of the fish as it cooks, coagulating on the surface. Canned, smoked or poached salmon are especially prone to albumin formation, but a small amount of the protein will appear on the surface of even perfectly-cooked fish.
Overcooked salmon, however, will have even more albumin on its surface, so the best way to avoid it is to be careful not to overcook your fish. Glazing the salmon in recipes like our Simple Salmon Teriyaki also seems to help.
