Chai means tea.
And this is apparently how you make it. Read the comments that go along with the instructions (forget the comments on the blog post), people get so passionate over their tea.
PS I like my milk with tea personally, Earl Gray or some sort of English Breakfast... but probably not the stuff you'd get here, it was just black tea from a tin, pitty I can't remember it's name. Over in england they drink it like coffee.
PSS I can't believe I still haven't finished posting these pictures. I don't think I even got to half of them. This set is the british Museum.
