Watermelon Mojitos


Cold, fizzy, and so refreshing – these watermelon mojitos are a twist on the classic Cuban drink. Made with fresh watermelon juice, rum, mint, and Iime juice it’s a great drink for a warm summer night.


  • 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


  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.


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.
