For a richer flavor, consider using an orange-infused simple syrup. Adjust the simple syrup to your liking, depending on the sweetness of your clementines. Use high-quality bourbon for the best results. A wheated bourbon or one with citrus notes complements the clementine flavor well. Large format ice cubes melt slower, preventing your cocktail from becoming overly diluted. For a non-alcoholic version, replace the bourbon with sparkling water or club soda.
