- Fresh Lime Juice: Brightens the cocktail and cuts through the sweetness.

For this easy recipe, you'll want to have on hand a cocktail shaker, shot glasses, spouted measuring cup, measuring spoon, and muddler.

- Ginger Ale: Use in place of club soda for a spicier fizz.

- Add Fruit: Muddle a few strawberries or cucumber slices for more complexity.
- Use Frozen Watermelon: Works well as ice cubes that won’t dilute the drink.
How to Make a Watermelon Mojito
Look at how simple it was to make this quick cocktail.
In a cocktail shaker add mint leave and muddle about 5-6 times to release some of the oils.
Fill about halfway with ice, then add watermelon juice, rum, simple syrup and half a lime (or more).
Shake until chilled and strain into a glass with ice.
Garnish with watermelon cubes and fresh mint leaves.
If desired, top with club soda.
Hint: Use ripe watermelon — a good watermelon has deep color, firm flesh, and plenty of juice.

How to Serve a Watermelon Mojito
This bright and bubbly cocktail is best served in a way that shows off its fresh ingredients and vibrant color.
- Shaken: Shaken — give it a quick shake in a cocktail shaker with ice to chill and blend before pouring over fresh ice.
- Glass: A classic mojito is served in a highball glass or tall Collins glass to allow plenty of room for club soda, mint, and ice. We serve our watermelon version in a lowball for casual gatherings.
- Garnishes: Top with fresh mint leaves, a few small watermelon cubes, and a lime wheel or wedge. For a festive touch, add a watermelon slice perched on the rim or a mint sprig tucked into the ice for aroma.
