This chilled drink combines fresh mint and lime juice with sugar-free mango syrup for a tropical, fizzy consistency. It has a zesty and sweet flavor profile as a sugar-free chilled drink that can be served as a cocktail or mocktail for warm afternoons.

About This Recipe

To release the aromatic oils of the mint, the leaves should be muddled gently in the bottom of the glass with fresh lime juice before adding the other liquids. The sugar-free mango syrup is stirred in to provide a fruity base that mimics the sweetness of a traditional mojito without the use of sugar. Filling the glass with plenty of ice and topping it with sparkling water ensures the drink remains cold and maintains its carbonation during service.

The flavor relies on the balance between the tartness of the limes and the cooling sensation of the fresh mint leaves. Using a mango-flavored syrup or extract allows for a tropical taste while keeping the drink low in carbs compared to using fresh fruit purée. Because the sparkling water provides the bulk of the drink, the intensity of the flavor can be adjusted by varying the amount of lime or syrup added to the glass.

This drink is quick to make and works well when served in chilled glasses for immediate consumption. It’s easy to customize by adding a splash of white rum for a classic cocktail version or keeping it as a mocktail for a lighter option. It is best served garnished with extra mint sprigs and lime wedges to enhance the citrus aroma and the visual presentation of the drink.
