I used to make iced tea like this - which is the usual way, I think, unless you use a mix. Boil the water, steep the tea, and chill. But last year Carmella said she just puts cold water in a pitcher with tea bags and refrigerates it, removing the bags the next day. What an idea!
So that's what I do now, except I put it in a half-gallon mason jar and it goes fast.
