Audibly leave complaint and drink (7,4)
I believe the answer is:
dessert wine
'drink' is the definition.
(dessert wine is a kind of drink)
'audibly leave complaint' is the wordplay.
'audibly' shows a homophone (sound like).
'leave' becomes 'desert' (desert can mean to leave or abandon).
'complaint' becomes 'wine' (I can't explain this - if you can you should give a lot more credence to this answer).
'desert' is a homophone of 'dessert'.
'dessert'+'wine'='DESSERT WINE'
'and' is the link.
Can you help me to learn more?
(Other definitions for dessert wine that I've seen before include "Alcoholic accompaniment to pud" , "Alcoholic accompaniment for 6, say" , "Tokay or Sauternes, for example" .)
