KITCHEN TIPS: To make a bigger batch of this cocktail (8 servings), place fresh mint leaves, lime wedges, and pomegranate arils in the bottom of a pitcher. Add 2 cups rum, 2 cups pomegranate juice, 1 cup lime juice, and 1 cup Mint Simple Syrup. Cover and refrigerate until cold or ready to serve. Prepare glass as directed in step 1, pour into prepared glass, and finish with cold sparkling water and mint sprig.
To change this to a mocktail, replace the rum with an equal amount of pomegranate juice or simply add more sparkling water. Pomegranate juice will bring forward the pomegranate flavor and have a richer color, while adding sparkling water will make it lighter and bubblier.
