It can be cooked, minced, in ovens (7)
I believe the answer is:
venison
'it can be cooked' is the definition.
The definition suggests a singular noun which matches the answer.
'minced in ovens' is the wordplay.
'minced' indicates anagramming the letters.
'in'+'ovens'='inovens'
'inovens' is an anagram of 'VENISON'.
Can you help me to learn more?
(Other definitions for venison that I've seen before include "Meat - in ovens (anag)" , "Deer meat" , "Type of meat" , "Deer (as food)" , "Game" .)
