Dish available in US city no more (5)

I believe the answer is:

balti

I'm a little stuck... Click here to teach me more about this clue!

'dish' is the definition.
(type of curry)

I don't understand how the rest of the clue works.

(Other definitions for balti that I've seen before include "Pakistani curry dish, originating perhaps in 1970s' Birmingham" , "Indian style of cuisine originating in Britain" , "Indian cuisine cooked in two-handled dish" , "Indian restaurant cooking style" , "food from India?" .)

I've seen this clue in The Times.
