Buy and eat fresh peach (6)
I believe the answer is:
beauty
'peach' is the definition.
(both can mean an excellent example of something)
'buy and eat fresh' is the wordplay.
'and' is a charade indicator (letters next to each other).
'fresh' is an anagram indicator.
'buy' put after 'eat' is 'eatbuy'.
'eatbuy' anagrammed gives 'BEAUTY'.
(Other definitions for beauty that I've seen before include "Good looks" , "Eye-pleasing quality" , "See 12" , "She was wooed by the Beast" , "Camberwell - (butterfly)" .)
