Page on hindmost dish (7)
I believe the answer is:
platter
'dish' is the definition.
(platter is a kind of dish)
'page on hindmost' is the wordplay.
I cannot really see how this works, but
'page' could be 'p' and 'p' is located in the answer.
'on' could be 'at' (I've seen this in other clues) and 'at' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for platter that I've seen before include "old record?" , "Shallow serving dish" , "Salver" , "Large flat serving dish" , "Large flat plate" .)
