Should it contribute a carroty flavour? (6)
I believe the answer is:
ginger
'flavour?' is the definition.
(I know that ginger is a more specific form of spice)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for ginger that I've seen before include "Hot-tasting rootstock" , "Hot fragrant spice" , "Fred Astaire's dancing partner" , "Fred Astaire's partner - Greer's gringo (anag)" , "Light reddish colour or hot-tasting flavour" .)
