Meat it can be a sin to cook in the oven? (7)
I believe the answer is:
venison
'meat' is the definition.
(venison is a kind of meat)
'it can be a sin to cook in the oven?' is the wordplay.
I cannot really understand how this works, but
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found within the answer.
an anagram of 'sin' is 'nis' which is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for venison that I've seen before include "Type of meat" , "Flesh of deer" , "Game" , "Meat - in ovens (anag)" , "Deer (as food)" .)
