Liquorice flavouring (7)
I believe the answer is:
aniseed
'liquorice flavouring' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for aniseed that I've seen before include "Licorice-flavoured sweets" , "Pernod flavouring" , "Liquorice-flavoured seeds" , "Die sane (anag)" , "Plant" .)
