Adding smoke on a gas grill.
OK, for those of you, like me that like the convenience of a gas grill, but would like that natural smoke flavor here is what I did and it worked GREAT!
I purchased some apple wood chips(for grilling/smoking), soaked them for a couple of hours in water. I then partially wrapped them foil, leaving the top open. I laid them over the burner, but not in the direct flame. I wanted them to smolder, not flame.
Once the grill got hot, the wood produced a nice smoke without flame. The food was terrific. I cooked a couple of steaks before roasting the pork I was really wanting the smoke for. Very simple, effective method for adding that smoke flavor.
