It's made with two pots: the tea is brewed separately from the milk, which is simmered down until thick, and the two are only combined in the glass.
Strong-brewed black tea is mixed with a thick, slow-reduced milk base and poured into a small glass, giving a rich, creamy brew. Hyderabad's remaining Irani cafés, with their high ceilings and marble-topped tables, serve it alongside Osmania biscuits and buttered bun-maska.
