6 cups 1-inch cubes seeded watermelon (about 1/4 large melon)
4 tablespoons (about) sugar
Fresh mint leaves
Puree watermelon in processor (there should be about 4 cups). Mix in sugar by tablespoonfuls to sweeten to taste. Pour into 2 to 3 ice cube trays. Rinse mint leaves and place 1 leaf atop puree in each cube. Cover and freeze until cubes are solid, at least 4 hours and up to 2 days.
