Given food that keeps set, being whipped (6)
I believe the answer is:
flayed
'being whipped' is the definition.
(I've seen this before)
'given food that keeps set' is the wordplay.
'given food' becomes 'fed' (I've seen this before).
'that keeps' indicates putting letters inside.
'set' becomes 'lay' (laying is a kind of setting**).
'fed' placed around 'lay' is 'FLAYED'.
(Other definitions for flayed that I've seen before include "Stripped skin from or criticised severly" , "Excoriated" , "subjected to criticism" , "Stripped skin or hide off" , "Stripped the skin off a body" .)
