I was wondering if someone could offer some assistance. I will be going on a vacation this summer down in NC. The house we are staying at has a gas grill and I thought what better way to thank my in-laws than to treat them to some good BBQ. Are there any tips that anyone has for using a gas grill to smoke a pork butt? I am planning on buying one of those smoke boxes you see at home depot to get that authentic smoke flavor. But are there any things to look out for/be prepared for when I do this on the gas grill? I would assume I turn one side of the grill on low and place the meat on the other, unlit side? I am a novice to begin with, but I do have a little experience on a traditional smoker and I have the basic knowledge/concepts. Just looking for a little advantage to have this thing turn out well. Any feedback would be much appreciated.
