Gas grill: soaked wood chips vs. dry wood chips I have a gas grill and want to get some good smoke flavor in a pork shoulder I am cooking. I've done some looking around for the best way to use wood chips and have found conflicting ideas about if you should soak them or not. Does soaking the chips do something other than adding time to getting to the initial smoke?
If you're putting your wood chips directly on a fire, it's good to soak them (and that means real soaking--a few days--not an hour or two). This prevents the wood chips from actually catching fire, which can cause off flavors from combustion chemicals settling back on your food. Tastes kinda like a brand new telephone pole smells on a hot day. Tar/Creosote, and not a nice flavor.

But on a gas grill, if you've got your chips in a pan or wrapped in a fairly tight foil pouch, you needn't worry so much about the chips actually catching on fire. As long as they just smoulder, you're good to go.
