Salmon skin is often discarded, but when properly sourced and prepared, it can be a nutritious part of the fish, providing omega-3 fats, protein and other nutrients such as vitamin D and selenium.
Because contaminants can accumulate in fatty tissues, choosing salmon from reputable sources is important. Cooked skin-side down in a hot pan, it can also become crisp and flavorful, adding both texture and nutrients to the meal.
