Combine all the ingredients except the garnish in a mixing glass filled with ice and stir until chilled. Add a large sphere of ice to a chilled double old-fashioned and strain the drink into the glass. For the garnish, use a paring knife to slice a thick strip of zest from an orange. Twist it over the drink to release the essential oils and rub along the rim of the glass. Stud the orange zest with whole cloves and drape it over the ice sphere.
