1 cup sugar
1 cup water
For the lemonade:
watermelon puree
1 cup lemon juice
3–4 cups water
ice
sliced lemon for serving, optional
In a blender, combine the watermelon, water, and sugar. Blend on high for 1 minute to dissolve the sugar. Pour the watermelon puree through a fine mesh strainer. Don’t skip the straining part here, watermelon tends to feel a little gritty in your mouth when it’s pureed. Add the watermelon puree to a large pitcher, add the lemon juice and additional water, and stir well to combine. Serve over ice with sliced lemon as a garnish.
