Beat, as cream (4)
I believe the answer is:
whip
'beat as cream' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for whip that I've seen before include "Cat-o'-nine-tails" , "Lash for driving animals" , "Strip of leather with handle, for beating" , "Flog - steal" , "Beat (cream)" .)
