Smoke your bourbon. Pour at least a cup of bourbon into a decanter. Using the smoking gun and tube from your smoking box kit, insert the end of the tube into the decanter above the bourbon and allow smoke to fill the vessel (use the super easy package instructions to operate the gun). Cap the decanter, then swirl the bourbon around inside for 15 seconds. Open and allow smoke to escape.
Build your old fashioned. Place a large ice cube (I used a special ice mold from W&P to get mine so crystal clear) into a rocks glass like this one. Pour 2 oz of the smoked bourbon over the cube, then add bitters and syrup and stir for 5 seconds. Twist a strip of orange peel over the drink, then rub it around the rim of the glass and drop it inside.
Smoke and serve the cocktail. Reattach the smoking gun to the smoking box, then place the drink inside. Fill the box with smoke according to package instructions, using a small sprig of rosemary instead of the included wood chips. Let the cocktail sit in the smoke filled box for a few moments, then open and drink immediately.
