Talk about a large dish (7)
I believe the answer is:
platter
This clue could be a double definition.
'talk' is the first definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'a large dish' is the second definition.
(I've seen this in another clue)
'about' is the link.
Can you help me to learn more?
(Other definitions for platter that I've seen before include "pop record" , "Large shallow dish" , "main course" , "Large flat serving dish" , "Salver" .)
