Whipped borscht initially consumed (6)
I believe the answer is:
beaten
'whipped' is the definition.
(I've seen this in another clue)
'borscht initially consumed' is the wordplay.
'initially' says to take the initial letters.
'consumed' becomes 'eaten' (similar in meaning).
The initial letter of 'borscht' is 'b'.
'b'+'eaten'='BEATEN'
(Other definitions for beaten that I've seen before include "Formed or made thin by hammering" , "Well-trodden" , "Stuffed" , "Struck; defeated" , "Vanquished" .)
