i have a grilll with the flavor bars and this is what I do, it seems to work very well, leave your flavorizer bar over the burner, if you dont you will either burn a hole through the foil or your chips will catch fire. take a handful of chips and put them in a water bowl, let them soak for an hour or so,, then take two pieces of foil about 18 inches long and lay them together and fold all of the edges over , then take two handfuls of cry dry chips and put them on the foil , then take the other handful of wet and put them on top of the dry. Take another piece of foil same size and lay it on top, roll all of the edges real good, make it nice and tight, then poke 5-10 foles in the top and bottom of the pouch.
I have had real good luck with this method.
by the way I forgot to say, you need to take an old grate or buy a small one and just lay it over your flavor bars, when you do this it will hold all of your smoke pouches just fine.
