Curry ingredient (5)
I believe the answer is:
cumin
'curry ingredient' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cumin that I've seen before include "Curry-seasoning herb" , "Culinary spice" , "Aromatic seeds used in cooking" , "Aromatic seeds used for flavouring" , "Aromatic (curry) spice" .)
