- Big chunk of watermelon, about 1 pound, rind removed, cut into chunks
- 1/4 cup agave syrup or simple syrup
- 1/4 cup finely chopped fresh mint leaves
- 2 tablespoons white wine vinegar
- Combine the watermelon, syrup, mint, and vinegar in a blender or food processor, and purée until smooth (though there still may be watermelon seeds and shards of mint floating around).
- Pour the mixture into a strainer set over a small bowl to remove the solid pieces. Gently lift and stir the mixture to help the liquid pass through, without forcing any solids through the strainer.
