"What's wrong with a bag o' Lipton in hot tap water, eh?"
what you get is just that, a warm(ish) amber liquid, BUT is it Tea? No, Not by a LONG way!!! having said that, I went to breakfast in a little diner in West Chester PA on a previous trip and they made REAL tea, in a proper teapot that had been Warmed and using boiling water!! so it is possible, if rare.
