Each dish wrapped by expert (6)
I believe the answer is:
apiece
'each' is the definition.
(synonyms)
'dish wrapped by expert' is the wordplay.
'dish' becomes 'pie' (I've seen this before).
'wrapped by' is an insertion indicator (I've seen this in other clues).
'expert' becomes 'ace' (ace can informally mean very good).
'pie' inserted into 'ace' is 'APIECE'.
(Other definitions for apiece that I've seen before include "A head" , "for everyone" , "Per person" , "For or by each one of group" .)
