Cucumber & watermelon agua fresca

Instructions

1. Put the watermelon, cucumber, lime, sugar, ginger and 100ml cold water in a blender. Blitz together until smooth.
2. Place a fine mesh sieve over a large jug and strain the mixture through, pressing down with the back of a spoon, if needed. Discard the pulp and transfer the jug to the fridge to chill.
3. Divide the drink between 6 short glasses and add some ice cubes. Top up with the sparkling water, to taste. Garnish with the cucumber and lime slices to serve.
