3 cups watermelon puree
2 cups J Sparkling vintage Brut
1 cup water
1½ cup simple syrup (or mint simple syrup)
To make simple syrup, put equal parts sugar and water in a small pot. Bring mixture to a boil then remove from heat. For mint simple syrup, add ½ cup mint leaves, roughly chopped, as soon as mixture is removed from heat. When syrup cools, strain out leaves.
For granita, combine all ingredients in a shallow pan and freeze. Scrape to serve.
The granita can be served before a main course as a refresher, or with fresh sliced fruits and berries for a summertime dessert.
