Peel from cucumber in dustbin (4)
I believe the answer is:
rind
'peel' is the definition.
(I've seen this in another clue)
'from cucumber in dustbin' is the wordplay.
'from' indicates a hidden word.
'RIND' is hidden within 'cucumber in dustbin'.
(Other definitions for rind that I've seen before include "Outer edge of a bacon rasher" , "Fruit covering" , "Fruit skijn as of orange" , "Crust" , "Outer skin of citrus fruit" .)
