Indian yoghurt dish (5)
I believe the answer is:
raita
'indian yoghurt dish' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for raita that I've seen before include "yoghurt dish from India" , "Indian side-dish of cucumber and yoghurt" , "Yoghurt-based Indian condiment" , "dish in Indian restaurant" , "side order" .)
