Ice-cream flavor (7)
I believe the answer is:
vanilla
'ice-cream flavor' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for vanilla that I've seen before include "type of orchid" , "Bland" , "Without any extras - all vain (anag)" , "Flavouring from pod of certain orchids" , "Subtle flavour pod" .)
