Remove some cucumber as expired (5)
I believe the answer is:
erase
'remove' is the definition.
(to erase is to remove)
'some cucumber as expired' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'ERASE' is hidden within 'cucumber as expired'.
(Other definitions for erase that I've seen before include "score" , "Put out of mind" , "Rub out, expunge" , "Destroy recording on audio or video tape" , "Eliminate" .)
