His curate prepared bread and wine (9)
I believe the answer is:
eucharist
'bread and wine' is the definition.
(I've seen this before)
'his curate prepared' is the wordplay.
'prepared' indicates an anagram.
'his'+'curate'='hiscurate'
'hiscurate' is an anagram of 'EUCHARIST'.
(Other definitions for eucharist that I've seen before include "Mass" , "Holy Communion" , "church service" , "host" , "Bread and wine" .)
