Centre in a fresh fruit (9)
I believe the answer is:
nectarine
'fruit' is the definition.
(nectarine is a kind of fruit)
'centre in a fresh' is the wordplay.
'fresh' is an anagram indicator.
'centre'+'in'+'a'='centreina'
'centreina' anagrammed gives 'NECTARINE'.
(Other definitions for nectarine that I've seen before include "Trace nine to a kind of peach" , "Fruit - aren't nice (anag)" , "Kind of peach with thin skin and no down" , "Smooth-skinned fruit" , "creating a sort of jam" .)
