Ingredients

The ingredients in this cocktail are simple, but they work together in a way that feels layered and refreshing. Each one adds something important to the overall flavor.

• 1.5 oz white rum
• 1 oz lime juice
• 1 oz cucumber purée
• 0.5 oz simple syrup
• 4 watermelon slices seedless
• 5 –6 mint leaves
• Club soda to top
• Garnish: cucumber slice and watermelon wedge

Fresh ingredients really matter here. The watermelon should be ripe and sweet, since it acts as a natural flavor base. Cucumber purée adds a smooth, cooling element that balances the sweetness. Lime juice brings brightness and keeps the drink from feeling too soft.

Mint is key in any mojito style cocktail. It adds aroma and freshness that you’ll notice right away. Club soda finishes the drink with a light, bubbly texture that makes everything feel more refreshing.

Suggested Liquor Brands and Substitutions

Since this cocktail is built around fresh flavors, you want a rum that complements rather than overpowers. A clean, light white rum works best.

• Bacardi Superior A classic choice with a clean and neutral profile
• Havana Club 3 Year Slightly richer with a smooth finish
• Plantation 3 Stars A balanced blend that works well in mojitos
• Don Q Cristal Light and crisp, great for refreshing cocktails
• Coconut water instead of rum For a non alcoholic version with a tropical feel
• Agave syrup instead of simple syrup For a slightly richer sweetness

If you want to experiment, you can also try a lightly flavored rum, but keep it subtle so it doesn’t overpower the fresh ingredients.

Equipment and Glassware

You don’t need anything complicated to make this cocktail, which makes it easy to prepare at home.

• Cocktail Shaker
• Muddler
• Jigger
• Bar Spoon
• Fine Mesh Strainer
• Highball Glass

A highball glass works best because it gives enough space for ice, soda, and all the fresh ingredients. If you don’t have a muddler, the back of a spoon can work just fine.

How to Make It

This cocktail uses a mix of muddling and shaking to bring out the best flavors. It’s simple once you get the steps down.

1. In a shaker, muddle the watermelon, mint, and lime juice. Press gently to release the juices and oils without over crushing
2. Add the cucumber purée, rum, and simple syrup. This builds the base of the drink
3. Fill with ice and shake gently to chill and mix. A light shake is enough here
4. Strain into a highball glass filled with fresh ice. This keeps the texture smooth
5. Top with club soda and stir lightly. Just enough to combine without losing the bubbles
6. Garnish with a slice of cucumber and a small watermelon wedge

Once you’ve made it a couple of times, you can adjust the balance depending on how sweet or citrusy you like your cocktails.

Storage and Serving Notes

This cocktail is best served fresh, right after making it. The mint and soda don’t hold up well if left sitting too long.
