Wild-caught salmon from the Pacific (Alaska and Washington) is considered the best choice for the environment because it is more sustainably fished and has a larger, more stable population. Farmed salmon, including Atlantic, should be avoided, as it endangers the wild salmon population.
To skin salmon, place fillet on a clean cutting board, skin side down. Starting at the tail end, slip the blade of a long, sharp knife between the fish flesh and the skin, holding the skin down firmly with your other hand. Gently push the blade along at a 30° angle, separating the fillet from the skin without cutting through either.
