Relatively unknown in much of the United States, walleye are a very popular favorite in the northern Midwest (particularly Minnesota) among eaters and anglers alike. While mild in flavor, they’re rich in protein and omega-3s, firm of flesh, and are well-suited for a variety of preparations. By the way, their name refers to the fish’s opaque, cloudy-looking eye, which is caused by a reflected layer of pigment that helps the walleye see in low light.
