Liquorice flavour (7)
I believe the answer is:
aniseed
'liquorice flavour' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for aniseed that I've seen before include "Liquorice-flavoured seeds" , "Flavouring herb" , "Licorice-flavoured sweets" , "Cake flavouring" , "Flavouring of sambuca" .)
