On the grill
Removing the backbone and pressing the bird flat lets it sit evenly over indirect heat instead of cooking unevenly around an awkward shape. It roughly halves the time versus a whole trussed bird.
Check the thickest part of the breast and the innermost part of the thigh separately — thigh needs to go further than 74 °C to be genuinely good, breast does not.
