Step 1

Use a crusher to crush the watermelon and mint leaves and release the juices in a pitcher. Alternatively, blend the cubed watermelon in a blender, until smooth, working in batches if needed. Pour mixture through a strainer into a large, clean pitcher. (You may discard the solids as they will be without flavor)

Step 2

Add concentrated ginger syrup and lime juice, stirring to combine. Stir in the sparkling water. Taste for sugar, ginger, or lime and add according to preference. Pour into a glass over ice, and garnish with a sprig of mint. Want to make this boozy? Just add a splash of vodka or tequila!
