Here is something I picked up in a Korean restaurant in London: iced water and a tea bag. I had to try it, and today is the perfect day since we are having a proper heat wave here, with 19 degrees outside! I am wearing a dress! Bare legs! I bought a black tea with orange flavour (something I would never drink warm), and you know, it´s really good! I am pretty sure the girl I saw drink it used green tea, but for some reason that gives me nausea.
I did drink a lot of iced tea when I was in Iowa as an exchange student, but that was made from hot tea mixed with sugar and lemon, and then iced. Nowadays I find that too sweet but this is just perfect, and so easy!
