This is more of a tip than a recipe, however, I have fallen in love with iced tea. I was visiting my parents, well about a year ago now, and in the back of the cabinet (I have grocery shopped many times in my parents cupboards) and found a box of Passion Fruit Iced Tea from Starbucks. According to mom, my sister had bought it and brewed a cup for herself - the problem being, the bags are intended to make a pitcher at a time. Mom happily sent it home with me (Sorry, Samantha).
I have really grown to love the stuff, finding it floral and spicy, but quite sour. I added simple syrup (equal parts sugar and water boiled so it incorporates into cold liquid), and it was great. The only thing that makes it better - the frozen strawberries I keep in my freezer for impromptu smoothies used as ice cubes.
P.S. For those of you in the Madison area, Bluephies has the best iced tea.
