Shake all of the ingredients (minus the 2 extra orange slices and nutmeg) with ice, and double strain into smoked glasses.
Grate fresh nutmeg over each cocktail, and serve with a slice of orange.
To smoke the glasses: light two cinnamon sticks on fire. Once the fire catches, blow it out, and place the cocktail glasses over the smoking cinnamon sticks for about 30 seconds. Immediately fill the glasses with the cocktail.
Notes
Recipe Pro Tips:
I think this recipe is great as-is, but substituting the bourbon whiskey with your favorite rum, brandy, or cognac.
Make this alcohol-free by omitting the bourbon whiskey. It's a delightful spiced tea!
