TO TRUSS

Tying a bird or a joint into a compact, even shape so that it cooks at one rate instead of several.

Why it works

An untrussed chicken is a collection of parts with very different thicknesses and very different heat requirements. Breast meat is lean and dries out above about 68°C; thigh meat is full of connective tissue and is only really good past 74°C. Left splayed, the thin extremities and the outer breast are fully exposed while the thigh joint sits shielded, so the breast overshoots long before the thigh arrives. Trussing pulls the legs in against the body, closing the cavity and shielding the inner breast, which narrows the gap between the two. It does not eliminate it — nothing does, which is why spatchcocking takes the opposite approach and flattens the bird so everything is exposed equally. Both are valid; they solve the same problem in opposite directions.

How to tell

The bird sits stable on the board without rocking, and the legs stay drawn together without being held.
The wing tips are tucked behind the shoulders rather than protruding, since they are the first thing to burn.
The string is snug enough to hold shape and not so tight that it cuts into the skin as the meat contracts.
The cavity is closed, which is what stops hot air circulating through the middle and drying the inner breast.

When it goes wrong

Breast is dry by the time the thighs are done.: The fundamental problem trussing only partly solves. If it persists, spatchcock instead, or cook the bird breast-down for the first half.
Wing tips are black.: Not tucked. They have almost no mass and burn long before anything else is ready.
String cut into the skin and the legs tore.: Tied too tight. Muscle contracts as it cooks, so a truss that was snug raw becomes tight hot.
The skin between leg and body stayed pale and flabby.: The inevitable cost. Trussing shields that area from heat, which is exactly why the breast underneath survives — you are trading crisp skin there for moist meat.

Recovering it

A bird that is drying at the breast can be turned breast-down for the remainder, which shields it and lets the thighs catch up. Burnt wing tips are simply removed. If the breast is already overcooked, carve the two halves separately and return the legs to the oven — serving the parts at their own doneness is far better than waiting for the worst of them.
