Rose Lime Granita

What better dessert for the last hot days of summer than a refreshing and light granita?  I made this one with Royal Rose Rose Syrup and lime juice, but you could use whatever syrup and citrus you have on hand.

4 cups water
2 oz. Royal Rose Rose Syrup (or more or less to taste)
juice of 1 lime

Combine ingredients and pour into a baking dish or casserole so that there is about 1 inch of liquid.  Place in the freezer for an hour, remove, and use a fork to scrape the ice.  Refreeze until solid.  When you are ready to serve, scrape the icy granita up with a fork and serve in a cup or bowl.
