Sweet baby Rays...any flavor, my ultimate favorite BBQ sauce. Honey chipotle, and hickory and brown sugar are mt two flavors.
Regardless of what sauce I use, I like to put the chicken in a pot full of water with about a cup full of barbeque sauce added. (I sometimes add an onion and/or garlic powder to the water.) I boil the chicken until it is fully cooked then I coat it with more barbeque sauce and put it on the grill. I use the grill to cook the barbeque sauce into the outside of the chicken, but I don't have to worry whether or not the chicken is getting cooked because I know that the boiling already cooked it. This method works great for ribs too.
DON'T EVER BOIL RIBS!!!!!!!! that is a cardinal sin and you should be tarred and feather for even suggesting people do it. now as far as BBQ sauce, it has probably been 10 years since I bought any sauce. I use my vinegar sauce for my pork butt and my memphis sauce for everything else.
YES, THIS ^^^^^^^I like several that have been mentioned, also Montgomery Inn sauce.
