Stuff relish between the skin and meat of the chicken. Tie chicken with the twine to hold the wings and legs against body. Rub oil onto skin of the chicken. Place Flav-o-buds in the chip tray or chip drawer. Place the chip tray in the rear corners of the drip pan or slide the chip drawer back in slot. Preheat the grill until chips start to smoke. Grill the chicken 1 to 1 one-half hours or until done. Insert fork into deepest part of thigh. Juices will run clear when the chicken is done.
