Remove the peel from (4)
I believe the answer is:
pare
'remove the peel from' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pare that I've seen before include "Strip the skin from" , "Shave, say, pencil" , "Trim by slicing" , "Cut down gradually" , "Whittle" .)
