Fruit — dish out entire can? (9)
I believe the answer is:
nectarine
'fruit' is the definition.
(I know that nectarine is a fruit)
'dish out entire can?' is the wordplay.
'dish out' indicates an anagram (I've seen 'dished out' mean this).
'entire'+'can'='entirecan'
'entirecan' anagrammed gives 'NECTARINE'.
(Other definitions for nectarine that I've seen before include "Kind of peach with thin skin and no down" , "Trace nine to a kind of peach" , "type of tree" , "Fruit - aren't nice (anag)" , "Smooth-skinned fruit" .)
