or at least my version of it. I ran all the flesh of a seedless watermelon (no rind) through the juicer. Poured the resulting juicing into this Pyrex dish that has a lid and put it into the freezer. A little over an hour later, I pulled it out and scraped the forming ice crystals into little pieces. Throughout the afternoon, I repeated that scraping process about every hour or so. After dinner, I served a generous scoop into a bowl. *mmmm* Delicious, cool refreshment.
Most granita recipes seem to call for the addition of sugar, maybe some water and a squeeze or two of citrus. Do so if you wish, but my results were just fine with only the watermelon juice. Enjoy!
