Grand Marnier flavor (6)
I believe the answer is:
orange
'grand marnier flavor' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for orange that I've seen before include "Fruit; pigment" , "juicy snack" , "Kind of sauce" , "Go earn the fruit" , "Name of reigning house of the Netherlands" .)
