1 To a large pitcher add the lukewarm water, granulated sugar, and freshly squeezed lime juice. Stir vigorously until the granulated sugar has dissolved completely.
9 In a blender or food processor, add the fresh cubed watermelon and lime zest. Blend until it becomes a juice. There should be 4 cups of watermelon juice.
7 Place a fine-mesh strainer over the top of the pitcher. Pour in the watermelon juice and press to extract all the juices. Stir together until combined, and discard the pulp.
6 Chill prior to serving or pour into glasses over ice. Feel free to garnish with a sprig of mint, lime slice, or a mini wedge of fresh watermelon like I did.
