Place all ingredients in a blender or food processor and pulse on low until blended and smooth.
Pour mixture into a 9″ x 13″ glass dish, cover with plastic wrap, and place in freezer for 3 hours.
Remove from freezer and using a fork, scrape the top layer of the mixture, and around the sides, working toward the center, to loosen it from the pan. The mixture will not be completely frozen. Return to the freezer for another 2 hours.
Repeat the scraping process again. Then repeat the freeze-scrape process until all parts of the remaining mixture has been frozen and scraped into flaky crystals.
Serve or store in a tightly sealed container in the freezer for up to 1 day.
Spoon into ice cream dishes, martini glasses or other stemware. Add a garnish of your choice. Eat with a spoon like Italian ice. (Serves 8.)
