This recipe is perfect, no changes need to be made. It always turns out great and it is the easiest recipe that I have for chicken on the (Weber) grill.
This became my go-to grilled chicken recipe last summer. I like to butterfly/spatchcock the chicken instead of quartering it, and then cook it over a two-level fire, with the leg quarters closest to the hotter side of the grill. I like the presentation butterflied, and it takes just a couple minutes longer on the grill.
