Spice used in goulash (7)
I believe the answer is:
paprika
'spice used in goulash' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for paprika that I've seen before include "Powdered pimiento" , "Red pepper powder used as a seasoning" , "Powdered sweet pepper spice" , "Powdered seasoning made from dried pimientos" , "something spicy" .)
