Like a lot of people have done the past few months I’ve taken to making my own cocktails and adult-beverages at home. It started with the citrus margaritas and sparkling vodka lemonade I shared in June and the trend continues. Not so much because I can’t go out to have a drink, but because I actually prefer my little happy hours on the patio these days.

And now it’s August and I’m still going strong and adding a watermelon mojito to the mix – a combination of fruity, minty, and fizzy stirred together in a glass along with rum.

Maybe it’s the pleasant evening happy hours and homemade drinks, but for the first time ever I’m not wishing August away so we can get on with fall which, normally, is my favorite season. This year, for obvious reasons I suspect, I’m wishing for summer to slow down. But, I know it won’t so I’m making the most of it.

If you’re the same, a great way to make the most of it is to make a batch of these refreshing watermelon mojitos. It’s like summer in a glass.

Mojito with Fresh Watermelon Juice

I’ve long been a fan of the mojito, a minty, refreshing rum cocktail that hails from Cuba, and only recently started giving it a watermelon twist. Mint and watermelon are a great combo and it’s a fun way to switch up this classic drink. Here’s what you need to make it:

  • Watermelon
  • Sugar
  • Fresh mint leaves
  • Lime juice
  • Rum
  • Ice
  • Soda water

For the watermelon, just puree it in a blender. I like to strain it twice – once after blending it and then again when I add it to the drink. The second strain is more about aesthetics as it just cuts down on the foaminess and makes for a prettier drink.

I’ve noticed you can buy watermelon juice at the store and using it will eliminate a big step and save some time. If you opt for the shortcut, I would omit the added sugar if the juice you buy is already sweetened.

Place the mint leaves, sugar and lime juice in glasses and muddle them. If you don’t have a muddler you can DIY it with the handle of a wooden spoon.

Lightly crush the mint leaves so they release their oils which will flavor the drink.

Add ice, rum, and the watermelon juice. As I mentioned, I like to pour the juice through a fine-mesh sieve into the drink to make it purty.

Top it all off with soda water, give it a stir and garnish with mint leaves and/or lime slices.

Pro tip: Make yourself a watermelon mojito soon. Summer won’t last forever, friends.

Happy cocktail-ing,

Ingredients

Scale
  • 4 to 5 mint leaves
  • 1 teaspoon granulated sugar
  • 1 lime, sliced in half
  • Ice cubes
  • 2 ounces white rum
  • 1/2 cup strained watermelon juice (see note)
  • Soda water

Instructions

  1. Tear the mint leaves in half and divide them between two glasses. Divide the sugar and lime juice between each glass (juice of 1/2 a lime per glass).
  2. Using a muddler (or handle of a wooden spoon) crush the mint leaves with the sugar and lime juice. Add ice to each glass.
  3. Add the rum and then pour the watermelon juice through a fine-mesh strainer into each glass (1/4 cup for each).
  4. Top the drink off with soda water, stir, and garnish with fresh mint and/or lime slices and serve.

Notes

For the watermelon juice, puree fresh watermelon chunks in a blender. Pour the puree through a fine-mesh strainer into a measuring cup. I like to strain the juice a second time when I add to the drinks which will reduce the amount of foaminess and makes for a prettier drink. 

If you buy premade watermelon juice check the ingredients. If it’s already sweetened you might want to omit the added sugar in the recipe and just muddle the mint with the lime juice. Otherwise, the drink might be too sweet.

  1. Refreshing, delicious cocktail. In place of soda water I used AHA sparkling water lime & watermelon flavor. Next time I’m going to try watermelon “juice” instead of fresh watermelon, just to taste the difference.
