Cut of meat old menial cooked . . . (9)
I believe the answer is:
medallion
'cut of meat' is the definition.
'medallion' can be an answer for 'cut' (I've seen this before). I am unsure of the 'of meat' bit.
'old menial cooked' is the wordplay.
'cooked' indicates an anagram.
'old'+'menial'='oldmenial'
'oldmenial' with letters rearranged gives 'MEDALLION'.
Can you help me to learn more?
(Other definitions for medallion that I've seen before include "Mad O'Neill wins the award" , "Cut" , "Circular piece of meat - commemorative award" , "Decoration worn round the neck" , "prize" .)
