Stop mad bishop getting into barrel for Easter tradition (3,5,3)
I believe the answer is:
hot cross bun
'easter tradition' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'stop mad bishop getting into barrel' is the wordplay.
I cannot really see how this works, but
'mad' could be 'cross' (both can mean angry) and 'cross' is present in the answer.
'bishop' could be 'b' (chess abbreviation) and 'b' is present in the answer.
'barrel' could be 'tun' (tun is a kind of barrel) and 'tun' is present in the leftover letters.
The remaining letters 'ho' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for hot cross bun that I've seen before include "Food for Good Friday" , "seasonal treat" , "Symbolic food item" , "Easter treat" , "Teacake-like baked confection" .)
