There’s nothing better than watermelon on a cold slice of watermelon. Oh wait, there is! Watermelon granita! This is one of the most refreshing things you can treat yourself to on a long hot... day. When our founder was in chemo, watermelon was one of her mainstays. It enabled her to hydrate when water tasted metallic. The trick to safely eating watermelon during treatment is to buy a whole watermelon, wash the outside well, and cut into it with a clean sharp knife. The thick rind should keep it safe from microbes.
Puree the watermelon, lime juice, and basil until smooth.
Pour the watermelon juice into a 9 x 9 x 2-inch glass baking pan and put into the freezer. After 30 minutes, with a fork scrape to form flaky texture. Continue to scrape the surface every 30 minutes until you have a fluffy snowy consistency. Serve or keep in an airtight container in the freeze, scraping every so often to keep a light texture.
