I always use turbinado sugar when I rotis. a chicken, but always go lightly on the rub. Obviously, too much will burn. A lemon, some onion, garlic and some of the rub sprinkled inside the bird help with flavor. I'd say around and hour and forty five minutes to two hours and your bird will be done just right. Its hard to beat a really good rotisserie chicken! Good luck!
