A little extra smoke adds great flavor to grilled food. Smoking is easy on a charcoal grill—simply toss water-soaked wood chips on the coals—but on a gas grill, you can’t toss in chips directly because they could clog the gas pipe. You can buy a metal smoker box (some high-end gas grills come with one), but it’s easy to achieve the same effect with a homemade smoker pouch. Simply wrap a large handful of soaked wood chips in heavy-duty aluminum foil to make a pillow-shaped package. Poke holes on top to release smoke and set the pouch under the grill grate. Run your grill on high until you see smoke.
