Cut the watermelon in half and remove the rind and seeds. Whizz the flesh in a food processor. If the mixture is too thick, add water.
Pour into a jug/pitcher, stir in the gin and serve in small glasses with plenty of crushed ice, a sprig of mint and a melon triangle.
Mix It Up
Cantaloupe melon can be used in place of watermelon – due to its firmer texture whizz for slightly longer in the food processor. Lovely with a dash of elderflower liqueur.
