Try using Earl Grey Tea. It really makes a unusual tasting iced tea. The first time I tried it was several years ago at a family Thanksgiving dinner. My wife ran out of our usual "Constant Comment" blend of black spiced tea, so he improvised and use what ever she had and that was several Earl Grey tea bags. When it was served, I like it so much that I just couldn't stop drinking it. Now when we make iced tea it is always Earl Grey.
