Well, you gotta make a pot of tea, let it cool, add some (or lots depending on your preference) sugar, lemon slices (and lemon juice), LOTS of ice, and shove it in the icebox. You really have to experiment with the stuff till you get it right, because I don't think there really is a set recipe for iced tea. I use green tea instead and I try to make it really strong, yet I don't add as much sugar and I put lots of lemon. It's all relative to your tastes.
