Watermelon ice
Instructions:
- Remove the rind from the watermelon, cut the flesh into 2-inch chunks, and remove the seeds. Arrange in a single layer on a parchment-lined baking sheet or in a resealable plastic bag; place in freezer until frozen, about 1 1 / 2 hours. (Transfer to airtight freezer bags if not using immediately.)
- Place the frozen chunks in a food processor; process until smooth. Add the sugar, lime juice, and Campari; process until fully incorporated, about 5 minutes, scraping down as necessary. Freeze in an airtight container, at least 2 hours, until firm. Stir if the juice starts to separate from ice.
