Resentment when mafioso hogged most of the fudge (7)
I believe the answer is:
dudgeon
'resentment' is the definition.
(I've seen this before)
'when mafioso hogged most of the fudge' is the wordplay.
I cannot quite see how this works, but
'when' could be 'on' (I've seen this in other clues) and 'on' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dudgeon that I've seen before include "indignant state" , "Devil's Disciple" , "Anger" , "Deep resentment" , "feeling of resentment" .)
