How to Make It
Pour kombucha into a 13- x 9-inch glass or ceramic baking dish; freeze 1 hour. Scrape with a fork and stir; return to freezer for 30 minutes. Once fully frozen, scrape and fluff with a fork.
Toss berries, sugar, lemon zest, and lemon juice in a large bowl to combine. Let stand at room temperature 45 minutes, stirring occasionally.
Place 1/2 cup yogurt in each of 6 chilled parfait glasses. Top each serving with 1/2 cup berry mixture and 2/3 cup granita. Top with fresh basil or mint leaves, if desired. Serve immediately.
