1. In a small bowl, combine the first five ingredients. Pour 1 cup marinade into a large resealable plastic bag; add the chicken. Seal bag and turn to coat; refrigerate for at least 4 hours. Cover and refrigerate the remaining marinade for basting.
2. Drain and discard marinade from chicken. Using long-handled tongs, moisten a paper towel with cooking oil and lightly coat the grill rack. Prepare grill for indirect heat, using a drip pan.
3. Place chicken breast bone side down and grill, covered, over indirect medium heat for 20 minutes on each side or until a thermometer reads 170°, basting occasionally with reserved marinade. Yield: 10 servings.
