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