Cuban cocktail (6)
I believe the answer is:
mojito
'cuban cocktail' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mojito that I've seen before include "Minty cocktail" , "Cuban cocktail with rum as a base" , "'Cuban cocktail made from rum, lime etc (6)'" , "Cuban rum-and-lime-based cocktail" , "Mexican cocktail made with white rum and lime juice" .)
