  • 1 1/4 cups pureed seedless watermelon

  1. Place one cup of mint in a medium heat-resistent bowl; set aside.

  2. Place the sugar, water, and remaining 1 cup of mint in a medium pot. Bring to a simmer over medium heat, stirring, until the sugar has completely dissolved and the liquid is clear, not cloudy. The mixture should be reduced and a light syrupy consistency.

  3. Pour this mixture over the bowl with the dry mint. Allow to cool completely, then strain.
