What is a mojito?

The classic mojito is a delicious cocktail composed of a few simple ingredients: rum, sugar, lime juice, mint leaves and club soda.

It is a refreshing libation that perfectly balances sweetness, sourness and freshness. It can be easily customized with flavored simple syrups or by muddling fruits, as we do in this invigorating Watermelon Mojito.

Mojitos are said to have originated in Cuba, although the exact origin remains uncertain. According to Difford’s Guide, some variation of the recipe can be traced back to 1586 when Sir Francis Drake visited Cuba. While he failed to obtain gold, he left behind a drink recipe featuring crude rum, sugar, lime, and mint.

Today, the mojito has become a beloved fixture at bars, clubs, brunches, parties and girls’ nights. It is a quintessential summer refresher.

Tools & glassware

To craft a mojito at home, you’ll need a sturdy muddler. This handy tool helps mash fruits and herbs together. If you don’t have a muddler, you can use the blunt end of a wooden spoon.

Feel free to mix the cocktail directly in the glass. However, if you prefer a smooth drink without watermelon seeds or herb remnants, muddle the ingredients in a cocktail shaker or mixing glass, then strain the mixture into a cocktail glass through a fine-mesh strainer.

The fresh Watermelon Mojito is a straightforward cocktail that requires only a handful of fresh ingredients from your local grocery and liquor stores. Here’s what you need to add to your shopping list:


Let’s start with the star ingredient — fresh and juicy watermelon! Adding fresh chunks of watermelon imparts a fruity twist to the classic mojito recipe, making it the perfect cocktail for summertime. 

Opt for the freshest, juiciest watermelon you can find, preferably sourced from a local farmer’s market or grown at home. Here are some tips on choosing a good watermelon.

Fresh mint

Mint is the heart and soul of the mojito, so don’t hold back.

Look for fresh mint leaves. You can buy them in clear, plastic clamshell containers at the grocery store, near the salad greens. If you plan to make a large batch of mojitos (and perhaps some mint juleps too), check if your store offers mint in a larger bundle.

You can also pre-batch a mint simple syrup which makes it easier to infuse mint flavor without muddling.


Next up is the sweet component. I recommend making your own simple syrup using water and granulated sugar. My recipe takes less than 10 minutes and consists of just two ingredients.

Plus, it’s more economical than purchasing pre-made syrup. For a bolder mint flavor, add a few sprigs of mint to the syrup after it boils and let it steep while cooling. Remember to remove the leaves before storing.

Alternatively, you can use pure cane sugar in your mojito, but it will take longer to dissolve and require more elbow grease to muddle.

Lime juice

Lime juice plays a vital role in a mojito. Ideally, use freshly squeezed lime juice for the best results. 

You can muddle lime wedges instead of using lime juice, but remove the spent shells afterward.

Store-bought lime juice concentrate tends to be more tart than sweet and can overpower the cocktail, but it works great if you want to make a bunch of mojitos. Lemon juice also works as a substitute. 

Club soda

Adding a splash of soda water gives the drink a lovely effervescence.

You only need a small amount to brighten up the mojito and make it even more refreshing.

Lemon-lime soda or ginger ale will work, but I find them too sweet. Stick to plain seltzer water for the best results.

White rum

The classic mojito calls for rum as its alcoholic base. Opt for white rum, also known as silver rum or light rum, as it is clear in color and won’t alter the vibrant hues of this hot pink mojito.

Dark rum, such as gold rum or spiced rum, adds too much color but can still be used if preferred.

White rum is light, crisp, and perfect for mixing into cocktails like the Mojito. Popular brands for white rum include Bacardi and Mount Gay, both of which are excellent choices for this delightful summer drink.

Variations and substitutions

Here are a few ways to add a twist to make the best watermelon mojitos! 

  • Other melon mojitos: Experiment with fresh cantaloupe or honeydew instead of watermelon to create different fruit-infused mojitos.
  • Watermelon basil mojito: Replace mint with basil to create a delicious variation. Consider using basil syrup or muddling fresh basil leaves.
  • Non-alcoholic mojito mocktail: Transform it into a virgin mojito by substituting a zero-proof spirit such as Ritual rum alternative. Alternatively, omit the rum altogether for a refreshing alcohol-free beverage.
  • Frozen watermelon mojito: Blend all the ingredients with 2 cups of ice for a frosty delight.

How to make a Watermelon Mojito

Crafting this delectable Watermelon Mojito recipe is incredibly simple. Follow these steps:

First, cut your watermelon into chunks. Here’s a watermelon-cutting tutorial.

Simple syrup is poured into a glass over watermelon chunks and mint leaves.
A wooden muddler crushes watermelon pieces, mint leaves and simple syrup in a glass.

Place fresh watermelon chunks (approximately 15 one-inch chunks) and a handful mint leaves in a highball glass with your homemade simple syrup.

Use a muddler to gently crush the watermelon and mint to extract the essential oils and fresh watermelon juice. This process releases the essential oils from the mint leaves and the juicy goodness from the watermelon.

Rum is poured into a glass from a gold cocktail jigger over watermelon and mint.
Clear soda is poured over watermelon mojito ingredients in a glass.

Place ice cubes in the glass, filling it to the top. Add fresh lime juice and white rum over the ice.

Top it off with a splash of club soda, and give the mixture a gentle stir.

Garnish your Watermelon Mojito with a straw, a small watermelon slice, a lime wedge and a mint sprig.

No muddler? No worries! You can easily improvise with the end of a wooden spoon or even a regular metal spoon. Apply gentle pressure to release the essential oils from the mint leaves and squish the melon into a pulp.

Tips & tricks

Consider these tips to perfect your Watermelon Mojito:

  • Opt for the freshest watermelon you can find for the most flavorful results.
  • If you don’t have a muddler, use the blunt end of a wooden spoon as a substitute.
  • If you prefer a smoother cocktail without fruit chunks and muddled mint leaves, prepare the drink in a shaker or mixing glass, then strain it into your drinking glass.

What to serve with Watermelon Mojitos

Melon lovers will enjoy this drink alongside fresh melon wedges and other melon dishes, like this watermelon blue cheese salad or this cantaloupe and mozzarella salad.

It would also be great with your favorite Cuban foods, like a Cuban sandwich or Cuban egg rolls.

These would be perfect for a summer cookout alongside smoked hot dogs with all the fixings or some spicy chicken wings.

What alcohol goes well with watermelon?

The bright and fresh flavors of watermelon go especially well with many spirits, but most especially vodka, rum and tequila. These clear spirits let the natural color of the watermelon shine and perfectly complement the flavor.

What is the best rum for mojitos?

White rum, also known as silver rum, is the ideal choice for Mojitos. Its clear color allows the mint and lime flavors to shine through. Popular brands like Bacardi and Mount Gay are excellent options for creating the perfect summer Mojito.

  • 8-10 mint leaves
  • 1 ounce simple syrup
  • 1 ounce lime juice
  • 2 ounces white rum
  • 2 ounces club soda
  • small watermelon slice for garnish
  • mint sprig for garnish


  • In a collins glass or highball glass, add the watermelon chunks, mint leaves and simple syrup.

  • Top with ice, filling the glass all the way.
  • Add the lime juice and rum. Top with club soda.

When muddled, the melon does leave behind some pulp and seeds. If you prefer a clearer drink without texture, do this instead: Muddle the watermelon, mint and syrup in a cocktail shaker or mixing glass. Top with lime juice and rum. Then use a strainer to pour the mixture into a glass of ice. Top with club soda and garnish.
If you don't have a muddler, you can use the blunt handle of a wooden spoon.
