Sole is a member of the flatfish family well-known for its fillets. Its firm, white flesh and distinctly delicious flavor makes it highly prized, and is even considered by many as the finest of all fish. The most celebrated by chefs is the Dover sole for its mild, buttery sweet flavor and versatility and for its ease of filleting. The fish yields fillets that hold together well in a variety of recipes. Sole is very versatile when it comes to cooking as it can just as easily be oven-baked, grilled, poached, steamed, prepared en papillote, pan-fried or seared, sauteed or deep-fried. To bring out the full flavour of sole, fillets can be marinated in oil, lemon juice, white wine or soya sauce. The sole is also an excellent source of high-quality protein, rich in vitamin B and provides generous amounts of phosphorus, magnesium, zinc, selenium, iodine and iron.
