Spot odd skinned fruit (6)
I believe the answer is:
dapple
'spot' is the definition.
(synonyms)
'odd skinned fruit' is the wordplay.
'skinned' indicates the central letters.
'fruit' becomes 'apple' (apple is a kind of fruit).
The centre of 'odd' is 'd'.
'd'+'apple'='DAPPLE'
(Other definitions for dapple that I've seen before include "Mark(ed) with spots" , "Mottle" , "Patch of colour/light" , "mottled" , "Variegate with spots" .)
