I am going to barbecue 1/2 chicken on a gas grill. I want to use a water mixture with cider vinegar and salt, to baste while grilling. Can you give me any tips as I do this, like time and temperature?
Try a 'Beer Can Chicken' stand. Use an empty (or not) beer (or soda) can to hold your basting liquid and properly place the chicken on the holder (as pictured) and put that on the grill.
As the chicken cooks your basting liquid will steam your chicken to a wonderful effect. IF you keep your lid down the steam will have the effect of continuously basting your bird.
