What Is a Mojito?
A traditional mojito is a highball drink, meaning it is a mixed drink that combines alcohol with a larger amount of a non-alcoholic mixer. Originating in Cuba, classic mojitos contain ingredients native to the country including rum, lime juice, fresh mint leaves, and cane sugar that are muddled together and topped off with a dash of club soda. The end result is a sweet, flavorful, fizzy drink that has become very popular to drink in summer.

What Does Watermelon Mojito Contain?
Here are the simple ingredients to make this cocktail today:
- Fresh watermelon cubes – large chunks of seedless watermelon are used to form the base of the drink, creating a sweet flavor and adding a boost of nutrients, too. For an easy option, use pre-cubed watermelon from the grocery store.
- Fresh lime juice – a traditional ingredient in mojitos. We suggest using freshly squeezed lime juice.
- Honey or agave nectar – an optional ingredient that can be used in place of simple syrup for a touch of extra sweetness. If you snagged a fresh watermelon that’s at the peak of its ripeness, you probably won’t need to add any sweetener.
- Fresh mint leaves – a staple in true mojito recipes, their freshness brightens the flavor of the drink and enhances the sweetness of the fruit.
- White rum (also known as light rum) – substitute sparkling water or kombucha for a ‘mocktail’ version.
- Sparkling water or soda water – we recommend using plain or lime flavor.
- Ice cubes

How To Make Watermelon Mojito
This recipe comes together fast with just a few simple steps.
- Blend: Add the watermelon cubes to a blender or food processor, and pulse until a smooth, juice consistency is achieved.
- Combine: Add the watermelon juice, lime juice, and optional sweetener to a mason jar or glass, and stir to combine.
- Muddle: Divide the mint leaves among 2-3 tall glasses, and use the end of a wooden spoon or a muddler to muddle the mint, smashing the leaves until they’re darker in color and slightly wilted. Feel free to add a small squeeze of lime juice during this step to help the leaves break down more easily.
- Serve: Fill each glass of muddled mint 3/4 full with ice, and divide the watermelon juice mixture evenly. Add white rum to each glass. Or, for a mocktail, use sparkling water in place of the rum. Stir to combine, add a garnish of a fresh sprig of mint and a small slice of watermelon with or without the rind, and enjoy!
Strain the Watermelon Juice
If the watermelon juice appears pulpy after blending, pour it through a mesh strainer into a mason jar or large glass to remove any clumps or leftover pulp from the watermelon puree.
