Sorry, around here we smoke pork chops but we don't put BBQ sauce on them (at least not in a restaurant that knows how to cook pork chops.
BBQ sauce goes well on BBQ (sparingly, it ain't sloppy joes).
I do love me some smoked pork chops. As LowRyter said, a couple hours in the smoker and finished on the grill.
I am a dry rub kinda Q'er. And maybe a little sauce for the finish on the grill.
And speak of the devil, chops are in the smoker as I write this.
I hate to quote myself but it was damn good.
and geess...... I didn't even grill them...so tender and smoky (BBQ rub).
