Delicious aroma is swirling around Bishop before end of meal (9)
I believe the answer is:
ambrosial
'delicious' is the definition.
(ambrosia was the mythical food of the Greek gods)
'around bishop before end of meal' is the wordplay.
'around bishop' becomes 'ambrosia' (I can't explain this - if you can you should believe this answer much more).
'before' is a charade indicator (letters next to each other).
'end of' says to take the final letters.
The last letter of 'meal' is 'l'.
'ambrosia'+'l'='AMBROSIAL'
'aroma is swirling' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
(Other definitions for ambrosial that I've seen before include "Delightful" , "delicious" , "Divine" , "Like special food" , "Heavenly" .)
