Flavouring to transport off (7)
I believe the answer is:
caraway
'flavouring' is the definition.
(caraway is a kind of flavouring)
'transport off' is the wordplay.
'transport' becomes 'car' (car is a method of transport).
'off' becomes 'away' (synonyms).
'car'+'away'='CARAWAY'
'to' is the link.
(Other definitions for caraway that I've seen before include "Oil taken from it" , "Seeds used for flavouring" , "Aromatic plant" , "____ seeds, for cooking" , "Umbelliferous plant" .)
