Cod fish have a dense, white flesh that makes them perfect for almost any type of cooking method. Most of the cod sold in the United States are Atlantic cod, but many other fish are sold around the world using the same name. Cod are generally flash-frozen aboard the fishing vessel and sold in the frozen fish aisle of the grocery store. If you live on the Atlantic coastline, fresh cod may be available at certain times of the year.
