Once grill has reached proper temperature, add a small amount of smoking chips, about 2 oz. Once the wood stops smoking, about 20-30 minutes, add more chips, but stop adding after the first hour of cooking so as not to over smoke the meat.
*Note, this recipe doesn't call for soaking your wood chips. I've tried cooking with soaked chips and with chips that haven't been soaked, I get a better flavor from the chips that were NOT soaked. Not soaking your chips is no more of a fire hazard than barbecuing itself. Try it, you'll like it ;-)
