Consider this recipe a three-for-one: You can make as directed for a hot or iced tea; or, you can make a frozen granita by increasing the agave nectar to 1/4 cup, then straining the finished tea, adding 1/4 cup chopped mint, and freezing in a shallow dish. Once it begins to freeze (about 2 hours), scrape it with a fork every 15 minutes until it's completely frozen and crystallized flakes have formed, about 2 more hours.
