Maybe it’s the summer 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, I wish for summer to slow down. But I know it won’t, so I’m making the most of it.

And so I’m still going summer drink strong and adding this watermelon mojito to the mix – a combination of fruity, minty, and fizzy stirred together in a glass along with rum.

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

How to Make the Drinks

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.

  • Method: Mix

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 pour the watermelon juice through a fine-mesh strainer into each glass (1/4 cup 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 foaminess and make for a prettier drink. 

I’ve seen watermelon juice at the store, and it will work in these drinks if you’re short on time. Just 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.

How to Make a Bigger Batch

Double or triple this recipe (or more) and make a pitcher of mojitos. Follow the same instructions, but instead of making the drinks in glasses, muddle the mint and mix it all in a large pitcher. It’s best to do this before you serve the drinks so the soda water doesn’t go flat.

Happy cocktail-ing,

  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.
