I'm trying this recipe this weekend and was wondering if I could get some ratios with the worchestire, mustard, and BBQ sauce. Also I was wondering if "Al's rub" is really important and what the "few of your other favorites are." Otherwise I'll probably just use garlic powder sinhce I'm not sure what the other seasoning's are. I never measure, but I'd say 1 part WS, 1 part mustard, and 3 parts BBQ. No, the rub specifics are not important, mine has brown sugar, garlic powder, black pepper, rotissiere chicken seasoning, and probably 2-3 others in it in smaller amounts. By far, garlic is 1st, then the rotissiere chicken seasoning, then all the rest.
