So you just wrap the chips in tinfoil and crank up that side of the bbq?
"Do you burn the wood or not? When using gas grills it's best to put presoaked wood chips in a smoker box or wrap them in a piece of aluminum foil with a lot of holes in it. This keeps your grill from filling up with ash and clogging the burners. But get that wood close to the heat. You need the heat to smolder the wood and this means a pretty high heat. If you are using a charcoal grill or smoker then you can either put the wood directly on the coals (once they've heated up) or place them in a box. Experiment a little and find out what works best for you.
Generally speaking any wood that is hard and free of resin (or sap) is good for making smoke. If the tree makes fruit or nuts you enjoy eating then the wood is typically good for smoking. Some wood, of course make better smoke than others. Woods like Apple have a mellow flavor and won't give you much in a short amount of time but if you’re cooking for a while then it has time to add that mellow flavor without overpowering the food. Woods like mesquite are very strong and while it gives you a good flavor quickly that flavor will become bitter fast so don't use too much or for too long.
Allow the wood to dry a little, you never want to apply wood that is dripping wet."
... and, from 'Doctor Smoke':
"Whether you choose to use wood chips or chunks, the main idea is to sustain the burn time of the wood. These woods are used not as a fuel source but to impart natural flavoring into the foods your cook. We recommend soaking the wood chips in either hot water, wine, beer, whiskey, or any flavoring you wish to impart into the food. No, you do not have to use only water for soaking! Remember, what you soak the wood in will also reveal itself in the flavor of the foods being cooked. The soak time will depend on the desired result. Dr. Smoke's easy rule regarding the soaking time is ... the stronger the flavor of the liquid, the shorter the soak time! So if your using a Merlot wine which has a strong flavor, you may only soak for 15 minutes. Using lemon juice, you may want to soak for up to 8 hours."
Wow, whiskey-soaked chips! Gotta try that.
