Combine all ingredients except the chicken in a shallow glass dish large enough to hold the chicken in one layer. Stir well to mix. Add chicken breasts, turning to coat both sides. Marinate, covered, in the refrigerator for 12 to 24 hours. Drain chicken from marinade and place on hot grill with the thin ends away from the flames. Cook, turning once, until just cooked through, 3 to 8 minutes per side, depending on heat intensity and thickness of meat. Do not over cook. Makes 4 servings.
