The Keto Mojito (Sugar-Free) is a chilled, fizzy drink that combines the aroma of fresh mint with the tartness of lime. By using a sugar-free sweetener and sparkling water, it maintains the crisp, cooling qualities of the traditional cocktail in a low-carb format.
About This Recipe
To extract the essential oils and juices, the fresh mint leaves and lime wedges should be muddled at the bottom of the glass with the sweetener before adding the liquid. Using white rum provides a neutral spirit base that allows the citrus and mint to stand out, while the sparkling water adds carbonation and lightens the drink. It is important to stir the mixture gently after adding the ice to ensure the flavors are distributed without losing the bubbles.
The flavor focuses on the balance between the zesty lime and the cooling sensation of the mint leaves. Liquid stevia or powdered erythritol can be used to provide a clean sweetness that dissolves easily in the cold liquid, avoiding any graininess. Because the drink relies on fresh aromatics, using bright green mint and juicy limes is what gives the cocktail its vibrant and refreshing profile.
This drink works well for relaxing at home or sharing with others and is easy to prepare in just a few minutes. It’s easy to customize by skipping the rum for a non-alcoholic mocktail or adding a few crushed berries for a different fruit note. It is best served immediately in a tall glass over plenty of ice, finished with a mint sprig and a lime wheel for a classic presentation.
