In a medium saucepan over medium-high heat, bring water and sugar to a boil. Stir until sugar is dissolved, about a minute or two. This is called a simple syrup. Set simple syrup aside to cool.

When completely cooled, add all remaining ingredients and stir to combine.

Pour mixture into a 9x13 inch pan and place in the freezer for one hour or until mixture begins to turn icy at the edges of pan.

Remove from freezer and stir with a fork, scraping icy mixture off of the edges. Return to freezer for another hour and repeat stirring to redistribute ice crystals. Mixture will be quite slushy at this point.

Return to freezer for another hour then stir again with a fork. Cover and freeze overnight or at least 4 hours.

An hour before serving, remove granita from freezer and use a fork to scrape frozen mixture down the length of pan forming icy flakes. Cover and return to freezer for 1 hour. Serve scoops of granita in pretty bowls. (Granita will not form a solid scoop like ice cream or sorbet, but will be more like a bowl of delicious flavored ice crystals.)
