A Better-for-You Cocktail!
This week on the blog we’re sharing four fruity, lightened-up, Better-for-You Cocktail recipes. Cocktails that are made with MUCH less sugar, are refreshing, easy-to-make, and are perfect for sipping on when the sun is shining and the temps are rising!
We’re kicking off the week with this Watermelon Mojito. A sparkling adult-beverage that combines lime juice, fresh mint, juicy watermelon, sparkling water, and white rum. It’s made with just 5-simple ingredients and no added sugar.
Looking for a non-alcoholic option? No problem. If you’d like to make this mojito a ‘mocktail’, simply omit the rum and add an extra splash of sparkling water, or even kombucha could work.
Watermelon Mojito Ingredients
Made with just a few simple ingredients!
- Large watermelon cubes – seedless watermelon works best. For an easy option, use pre-cubed watermelon from the grocery store.
- Lime juice – a traditional ingredient in mojitos and there’s just something about the combination of lime and watermelon. We suggest freshly squeezed lime juice.
- Honey or agave nectar – an optional ingredient that you can add for a touch of sweetness. If you snagged a watermelon that’s the perfect ripeness, you won’t need to add any sweetener.
- Fresh mint leaves – what makes a mojito a mojito.
- White rum – substitute sparkling water or kombucha for a ‘mocktail’ version.
- Sparkling water – plain or lime flavor.
How to make Watermelon Mojito
This recipe comes together fast with just a few simple steps.
First, you’ll blend the watermelon cubes in a blender to create a juice consistency. Now, if the watermelon appears to be pulpy or you prefer removing all particles from the watermelon, feel free to pour the juice through a mesh strainer and into a mason jar or large glass.
Next, add the lime juice and optional sweetener to the watermelon juice give it a stir. Note: because watermelon varies in sweetness, I recommend tasting the juice first before adding any sweeteners. There’s a good chance it will be sweet enough!
Now divide the mint leaves among 2-3 tall glasses. With the end of a wooden spoon (or a muddle) muddle the mint. Ultimately you want to smash the mint leaves until all leaves are darker in color and appear a little wilted. Feel free to add a small squeeze of lime juice during this step as it helps the leaves to break down a little better.
It’s time to make the drink! Fill each glass 3/4 full with ice. Divide the watermelon-lime juice among the 2-3 glasses. Add 1.5 oz. of white rum to each glass. For a ‘mocktail’, use sparkling water or kombucha in place of the rum. Top each glass off with a splash of sparkling water (lime flavor works great!). Stir and enjoy!
Can the watermelon juice be made ahead of time?
I recommend no more than 48 hours in advance. The juice really separates as it sets in the fridge so you’ll want to give it a good stir or shake before making the drinks.
Can I make it with store-bought, pre-made watermelon juice?
You sure could! You’ll need about 1 cup. You could also use GTS Watermelon Wonder Kombucha. I haven’t tried that yet but I think it would be really quite delicious!
