Whitefish is considered one of the best eating freshwater fish there is. Because the fish live in icy northern lakes, the meat has a high-fat content, making it an excellent candidate for smoking. Whitefish are more forgiving in regard to overcooking than leaner fish. For grilling, use skin-on fillets. Whitefish can also be used in seafood chowders or salads, since their meat is solid and holds together well.
