Fruit from can — entire bananas (9)
I believe the answer is:
nectarine
'fruit' is the definition.
(nectarine is a kind of fruit)
'can entire bananas' is the wordplay.
'bananas' indicates an anagram (bananas can informally mean crazy).
'can'+'entire'='canentire'
'canentire' is an anagram of 'NECTARINE'.
'from' acts as a link.
(Other definitions for nectarine that I've seen before include "Smooth-skinned fruit" , "Variety or mutation of a peach" , "Kind of peach with thin skin and no down" , "Trace nine to a kind of peach" , "fruity" .)
