Shake the rum, lime juice, and Demerara syrup in a shaker. Pour into a highball glass filled with crushed ice. Top with ginger beer and dash of bitters, garnish with a mint sprig.
Cocktail Shopping Tip
Buy your booze in bulk – transfer what you need into smaller bottles to stock your bar – you’ll save money and have enough leftover for your next party.
Cocktail Cooking Tip
Add another layer of flavor to your cocktails by making your own simple syrup – combine equal parts sugar and water with whatever aromatics you like – fresh herbs, whole spices, citrus, or chile peppers – heat to dissolve sugar and strain before using.
