Directions

1. Place half the watermelon, half the lime juice, and half the sugar in a blender. Process until smooth, then pour into a separate bowl.
2. Repeat with other half of ingredients. Pour into same bowl as other batch.
3. Transfer mixture to a 9 x 13 baking dish. Freeze for two or three hours, then begin the process of lightly scraping the top, frozen layer. Return pan to freezer with the shaved ice on top; remove a couple of hours later and continue scraping. Repeat the occasional scraping process until the entire mixture is shaved. Store, covered in plastic wrap, until serving.
4. Serve in pretty glasses with a twist of lime.
