After-dinner candy (4)
I believe the answer is:
mint
'after-dinner candy' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mint that I've seen before include "strike?" , "Place authorised to make a country's coins" , "Coin-making place or nice lamb sauce" , "Make coin - herb" , "Produce coins" .)
