In kosher butcher terms, turkey capons (often just called "capons" or "chicken capons" interchangeably) refer to boneless, skin-on poultry thighs that are neatly stuffed, rolled, and tied into elegant personal roasts. While historically a "capon" is a large, tender castrated rooster, modern kosher cuisine relies heavily on dark turkey thigh meat for this dish because its rich iron content and higher fat-to-meat ratio create a succulent, beef-like flavor profile that never dries out during baking.
