Trousser (to truss) and brider (to tie) are the essential techniques for preparing poultry and game birds for cooking, securing the limbs and shaping the bird into a compact, symmetrical form that ensures even cooking, elegant presentation, and easy carving. These two terms, while often used interchangeably, have distinct classical meanings: trousser specifically refers to tucking and folding the bird’s appendages into position, while brider refers to the actual tying with kitchen string (ficelle de cuisine). The classical French bridage uses a single piece of string and a trussing needle (aiguille à brider) to pass through the bird in two carefully placed passes. First pass: the needle enters through the drumstick joint on one side, passes through the body cavity, and exits through the drumstick joint on the opposite side; the bird is then turned, and the needle passes through the wing joints in the same manner. One length of string secures both passes when pulled taut and knotted. Second pass (for en entrée presentations): the needle passes through the tip of each drumstick and through the tail skin, securing the legs tightly against the body. The winglets are tucked behind the back before trussing — a simple fold that locks them in place without requiring string. Before trousser, the wishbone (os de la fourchette) is removed by carefully scraping along both prongs with a small knife and pulling it free — this crucial preparatory step makes carving the breast infinitely easier after cooking. For birds to be served whole at table, the string is removed after cooking and before presentation, as the set proteins hold the shape. The technique’s importance cannot be overstated: an untrussed bird cooks unevenly (legs splay, breast dries before thighs finish), presents poorly, and is difficult to carve. A properly trussed bird is a statement of professional competence.
Wishbone removed before trussing. Wings tucked behind the back. Single string through trussing needle for two passes. First pass secures legs and wings, second pass tightens drumsticks. String removed before presentation. Compact shape ensures even cooking.
Soak kitchen string in water before trussing — wet string grips better and doesn’t slip. When removing the wishbone, work from the neck cavity with the bird breast-down for better visibility and leverage. For birds that will be served whole, make the needle passes as close to the joints as possible to minimise visible marks on the breast and leg meat.
Forgetting to remove the wishbone. Tying too loosely, so string slips during cooking. Tying too tightly, leaving string impressions in the cooked skin. Using multiple separate pieces of string instead of the efficient two-pass method. Leaving string on for presentation. Puncturing the breast meat with the trussing needle.
