Sherry, dry vermouth and a medley of herbs make for a robust mix of flavors in Barbecue Chicken Marinade from Recipe Source. While it's best to use good-quality sherry (a liquor you would drink), you may substitute a low-sodium cooking sherry. The chicken should only need a matter of hours to soak in this mixture, unlike other marinades that work best with meats soaked overnight. You can also use this barbecue marinade as a sauce to serve with grilled chicken or even as a baste. However, baste with caution: Vegetable oil in the mixture can combust when it comes in contact with your grill's hot coals.
Combine all ingredients, and marinate the chicken for about three hours before grilling.
