This recipe fulfills the fantasy of grilled chicken that is both juicy and charred. Spatchcocking and slashing the bird allow it to cook evenly and remain succulent as the spiced honey and lemon marinade caramelizes into a golden crust. A low-temperature grill and attentive flipping are essential to cooking the bird through without singeing the outside. Pay close attention to the skin during the first few minutes of cooking to make sure the grill isn’t too hot, then turn and baste regularly to cultivate bronzed, savory-sweet skin.
