Did I describe my "house" iced tea mix? I never drank iced tea until I moved to Texas, and now I can't imagine life without it. To cut back on the caffeine, I use green tea. In a 2-litre glass jar I suspend 3 green tea bags and use a generous sprig (several inches long with several leafy stems) of lemon balm that grows unrestrained outside my back door (it escaped from a pot). After brewing I sweeten it with three level tiny scoops of Stevia. Once it's cold I put ice and a little water into a glass and fill it with the tea. The point of iced tea is not to be the same strength as a cup of hot tea, hence the extra water. If you use the hot tea to try to make a cup of iced tea the cubes melt too fast and it's too dilute. There is a sweet spot, when the tea is only a little warm, when you can start making a glass that will come out perfect. I make enough to drink for a couple of days, hence the added water once the tea is chilled.

I can drink this into the early evening and still get to sleep at night (I have to stop drinking black tea by early afternoon).
