Light the rosemary sprig and place it under an overturned glass to fill it with smoke. Let it sit while you prepare the drink. In a mixing glass, combine the syrup with bitters, then add bourbon and ice. Stir until chilled. Turn over the smoked glass, strain the cocktail in, and garnish with the smoked rosemary sprig and orange peel.

For a mocktail version, sub the bourbon for seltzer water

Enjoy!
