Watermelon Granita

What a sad life... too much watermelon... well, there must be some way to get rid of it. Right?

4 c. seedless watermelon, cubed
1/4 c. granulated sugar
1 tbsp. lime juice

Puree ingredients until smooth; DO NOT use a food processor unless you want sticky pink liquid all over the counter. Pour into freezer-safe 8x8 pan. Cover. Place in freezer. Come back in an hour - see, you can study and cook at the same time! - and whisk with a fork. It will probably not be remotely frozen yet. Return to freezer, this time for three hours or until ready for consumption- bet you can finish that pesky essay - and flake with a fork until the pink, watermelon-flavored brick achieves roughly the texture of shaved ice. Return to freezer in between quality control sessions, since otherwise you'll have to start all over again from the puree stage, keeping in mind that you'll have to re-flake it after it comes out of the freezer because it will have frozen solid.

A very refreshing, very easy, very low-calorie summer dessert that proves I can achieve deliciousness without butter, flour, chocolate, or an oven. Take that.
