Turducken

Turducken is a dish consisting of a deboned chicken stuffed into a deboned duck, further stuffed into a deboned turkey. Outside of the United States and Canada, it is known as a three-bird roast. Gooducken is an English variant, replacing turkey with goose. The word turducken is a portmanteau combining turkey, duck, and chicken. The dish is a form of engastration, which is a recipe method in which one animal is stuffed inside the gastric passage of another—twofold in this instance. The thoracic cavity of the chicken/game hen and the rest of the gaps are stuffed, sometimes with a highly seasoned breadcrumb mixture or sausage meat, although some versions have a different stuffing for each bird. The result is a fairly solid layered poultry dish, suitable for cooking by braising, roasting, grilling, or barbecuing.
