"Turkey necks are an often overlooked cut of the bird, as they have little substance compared to meatier cuts like breasts and wings. However, they are a welcome ingredient in many different dishes, and are adept at providing a deep and comforting flavor to many meals. Try this economical cut of meat to boldly season a dish or as an inexpensive main course, and be amazed at the taste explosion that a neck packs. Cook turkey necks slow and long to enhance their tenderness."
