fat hen or chicken parts disjointed

Fat hen, or poule grasse as termed in classical French cuisine, refers to a mature laying hen, typically 18 months or older, that has accumulated subcutaneous fat and intramuscular marbling due to age and continued egg production. These birds are substantially larger and fattier than younger broilers or fryers, with meat that is tougher but more flavorful due to the development of muscle fibers and connective tissues over time. The meat is darker and more pronounced in taste than younger poultry, with a yellow-tinted skin from the hen's diet of maize and forage.

When disjointed, a fat hen is broken down into constituent parts: thighs (with more connective tissue and fat), drumsticks, breasts (which remain relatively lean), wings, and the carcass reserved for stock. This butchering technique maximizes the ingredient's utility across different cooking methods and dishes, as each part has distinct textural and cooking properties.

Fat hen was historically the foundation of peasant and home cooking across Europe, particularly in French, Italian, Spanish, and Germanic cuisines, before industrial broiler production supplanted older birds in markets. Disjointed parts are ideal for braises, stews (coq au vin, fricassées), and slow-simmered preparations where the extended cooking time breaks down collagen into gelatin, enriching the braising liquid. The fatty thighs and drumsticks are excellent for poaching, pot-au-feu, and robust dishes requiring sustained heat; the breast meat, though drier, suits terrines and forcemeats. The carcass yields deeply flavored stock prized in professional kitchens. Contemporary interest in heritage poultry has renewed the use of fat hen in nose-to-tail and farm-to-table cooking.
