Notes
If you like your tea sweetened you can sweeten the tea to your liking using your favorite sweetener (sugar, stevia, Splenda, honey, agave nectar, etc.). If you are serving the tea to guests you may wish to set sweetener out for them so that they can add as much (or as little) as they wish. Or you can sweeten the whole batch before serving or before chilling (if making iced tea).
