you might be right, but Delia crying it 'iced tea' isnt going to help me convince my colleagues that im not a freak whenever i bring it to work! 
Fair enough. Mint and sugar are probably acceptable in the iced tea, but no juice. Delia should probably either embrace our tea traditions entirely, or not, but not go halvesies and call it "iced tea".

My mom does a nice tea punch with a darjeeling or green tea and cranberry juice. It's nice in the summer, very refreshing.
