Choice of fruit? (4)
I believe the answer is:
plum
This clue is a double definition.
'choice' is the first definition.
(both can mean excellent)
'fruit?' is the second definition.
(plum is a kind of fruit)
'of' acts as a link.
(Other definitions for plum that I've seen before include "Best; fruit" , "Very desirable thing" , "Purple fruit" , "Prize" , "Brilliant" .)
