Drink that has a charm about it (6)
I believe the answer is:
mojito
'drink that has a' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'charm about it' is the wordplay.
'charm' becomes 'mojo' (I've seen this before).
'about' means one lot of letters goes inside another.
'mojo' enclosing 'it' is 'MOJITO'.
Can you help me to learn more?
(Other definitions for mojito that I've seen before include "Mexican cocktail made with white rum and lime juice" , "Cuban cocktail with rum as a base" , "Cuban rum-and-lime-based cocktail" , "Minty cocktail" , "'Cuban cocktail made from rum, lime etc (6)'" .)
