How do I truss a chicken, and does it actually matter?

Trussing is one of those steps that recipes present as compulsory and that half of professional kitchens skip. It does something real — it just does not always do something you want. The sequence below is the simple version, and the drawing shows each stage.

What you'll need

• A metre of butcher's string or cotton kitchen twine
• A whole bird

Step by step

1. Tuck the wing tips first.Fold each wing tip up and behind the shoulder so it locks under the bird's own back, like a person putting their hands behind their head. This stops the thin wing tips burning and it stabilises the bird on the tray. Do this whether or not you truss the legs.
2. Find the midpoint of the string and hook it over the drumsticks.Sit the bird breast up with the legs towards you. Pass the middle of the string under and around the two drumstick ends, then cross the ends over each other so the drumsticks are pulled together and slightly upright.
3. Run the string back along the body.Take one end in each hand and pull them back towards the neck end, running each along the groove between the breast and the thigh. Keep tension so the string pulls the legs in against the body and traps the wings.
4. Turn the bird over and tie off.Flip it, bring the two ends together over the flap of neck skin and the tucked wings, and tie a double knot. Trim the ends short so they do not scorch. Turn it back over — the bird should now be a compact oval.
5. Decide whether you actually want it trussed.Trussing closes the cavity and pulls the legs against the breast. That protects the thin edges of the breast and gives a neater shape, but it shields the thigh joint from heat — and the thigh is the part that needs to reach a higher temperature. Untrussed, the legs splay and cook faster, which is usually what you want.
6. Use the compromise if you are undecided.Tuck the wings, tie the drumstick ends loosely together with a single loop, and leave the rest open. You get the tidy shape and the wing protection without shielding the thigh joints. This is what most roast chickens actually want.

Tips

• Use undyed cotton string. Synthetic twine melts and some coloured string is not food-safe at oven temperatures.
• If you are stuffing the cavity — which brings its own problems — trussing is genuinely useful for keeping the stuffing in.
• Trussing matters more for spit-roasting and rotisserie than for oven roasting, because loose limbs flail and cook unevenly on a spinning bird.
• For the fastest, most evenly cooked roast chicken, spatchcocking beats any trussing decision — it removes the problem rather than managing it.

Common mistakes

• Trussing tightly and then wondering why the thighs are underdone — A tight truss physically insulates the thigh joint from the oven. The breast finishes first, the thigh lags, and the gap between them widens.
• Leaving long string tails — They char, they smoke, and they are one more thing to fish out of the roasting tin. Trim to a couple of centimetres.
• Leaving the wing tips out — They are thin and unprotected. They blacken long before anything else is ready and they taste burnt if you eat them.
