Spatchcocked Chicken with Blackberry Barbecue Sauce

Chef notes

While the chicken is marinating and cooking on the grill, the barbecue sauce can be made. The chicken can rest and be served at room temperature. Blackberries are a great mid-summer fruit and complement the grilled chicken perfectly. The berries add a subtle sweetness to the sauce to play off the heat of the chiles and the acid of the vinegar.

Technique tip: Any remaining sauce will keep in the refrigerator for 1 week or in the freezer for 6 months.
