Sort of bread to consume, when outside (7)
I believe the answer is:
wheaten
'sort of bread to' is the definition.
I can't judge whether this definition defines the answer.
'consume when outside' is the wordplay.
'consume' becomes 'eat' (eating is a kind of consuming).
'outside' indicates putting letters inside (some letters go outside others).
'eat' placed into 'when' is 'WHEATEN'.
Can you help me to learn more?
(Other definitions for wheaten that I've seen before include "corny!" , "Like bread" .)
