I think I found the perfect ratio for using gunpowder tea for iced tea. Believe it or not, only one teaspoon per quart seems to be just about right.

Our iced tea maker has a three quart pitcher, so of course I only put three teaspoons of tea in the basket. It looks so ridiculously small before I start brewing, but after the tea leaves unfold, the fill the basket almost an inch or so. Weird.

I might try 2 ½ teaspoons of tea for the next batch just to see how that works.
