Skin On Bluenose fillets 1KG All fish come scaled, cleaned & boneless. Everyone knows that fresh fish & salmon are full of healthy fats, but much of those are actually stored in and around the skin. Omega-3’s, (known to help prevent heart attacks), are found in the fishes fat and this get absorbed by the skin during cooking. The skin will help the meat retain its moisture as it cooks. If cooked right, fish skin can bring a delightfully crispy dimension to a standard fillet. Lightly scoring the skin prior to placing it into the hot pan will stop the fillet curling.
