Spatchcocking, in four cuts

Poultry shears down either side of the backbone and lift it out. That is the first cut. Then turn the bird over and press down hard on the keel bone with the heel of your hand until it cracks — the bird should lie flat. Then tuck the wing tips behind the shoulders so they do not burn.

The whole job takes three minutes and it changes the cooking geometry completely. A whole bird has the breast on top of the legs, so the legs are shielded and cook slower while the breast is exposed and cooks faster — the exact opposite of what each piece needs.

Dry brine, and where the salt goes

A dry brine rather than a wet one, because the skin is the point of this cook and a wet brine guarantees it will be soggy. Salt at 1% of the bird's weight, applied 24 hours ahead, uncovered in the fridge.

Put half the salt under the skin on the breast and thigh and half on the skin. The under-skin salt seasons the meat; the surface salt dries the skin. Skip the sugar entirely — it will burn in four minutes over the coals.

  • 1% salt by bird weight, 24 hours ahead, uncovered
  • Half under the skin, half on it
  • No sugar, no oil until the bird goes over the coals
  • Black pepper only, applied just before cooking

Two zones, then a four-minute finish

One chimney of lit briquettes on one half of the grate gives 190°C at the lid with a spatchcocked bird on the other half. That is hotter than most barbecue, and it is right here: the bird is thin and flat, so it cooks fast and the skin renders rather than going leathery.

The last four minutes over the coals is what turns a good bird into a crisp one. Skin-side down, lid off, watching. Any longer and the fat in the skin renders out and the skin starts to burn rather than brown.

Cutting and serving

Eight pieces: two legs, two thighs, two wings, and the breast cut into two halves across the keel. Cut the breast across the grain at 1 cm and the leg at the joint, not through the bone.

Spatchcocked chicken does not hold. Ten minutes of rest and then serve; at twenty minutes the skin has lost its snap and no amount of reheating brings it back.

  • Eight pieces: 2 legs, 2 thighs, 2 wings, breast split into 2
  • Rest 10 minutes only, skin side up and uncovered
  • Leftovers are better cold in a salad than reheated
  • The backbone, if you kept it, goes into a stock with the wing tips

Slice direction: Across the bone, one thick slice per rib

Spatchcocking is the only way to get the breast and the leg to finish together. Laid flat, the legs are at the outer edge of the grate where the heat is highest and the breast is over the middle. Sliced across, the leg meat is visibly darker and looser and the breast is pale and tight, and both are correctly cooked.

Verdict: An hour and a quarter at 190°C indirect with a cherry chunk, then four minutes skin-side down over the coals. It is the fastest way to a whole bird with crisp skin and it beats any beer-can method by twenty minutes.
