Roadside Chicken

1 cup white vinegar
1/2 cup veg oil
1/4 cup Worcestershire sauce
1 TBS Sea or Kosher salt
1 TBS white sugar
1 tsp garlic powder
1 tsp onion powder
1 tsp white pepper
1/2 tsp celery salt
Mix/shake till well dissolved. I put mine in a old Worcestershire bottle with the shaker top. You can marinate the chicken in the sauce for up to 24 hrs before cooking. If so discard marinade and make fresh for the cooking sauce. I apply the sauce every 5 min to both sides and turn every 5-10 min. Apply one final coating 5 min before removing from the grill. You can't put too much sauce on while grilling. It will build up a nice layer of flavors. Hope you like it. Enjoy
EDIT: If you are going to marinate the chicken first, then leave the oil out for the marinade process. Make up a fresh batch for basting the chicken with the oil in the sauce.
