Smoke-y says.

Your next cocktail party will be on fire with this trick of the mixology trade. For a sophisticated, camp-y infusion, tuck your bourbon under that glass dome and use the handheld smoker to add a little intrigue to your happy hour (wood chips are included too). But don’t stop there! Cheese, meat (or anything you fancy really—but gouda is always a winner) can also go right on the black walnut base for some fancy smoke treatment.
