Type of long-grained rice (7)
I believe the answer is:
basmati
'type of long-grained rice' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for basmati that I've seen before include "Type of long-grained rice" , "Fragrant type of rice" , "Kind of long-grained rice" , "Fragrant long-grain rice" , "part of Indian order?" .)
