Batter with butter (3)
I believe the answer is:
ram
I believe this clue is a double definition.
'batter' is the first definition.
(I've seen this before)
'butter' is the second definition.
(a ram is something which 'butts')
'with' is the link.
(Other definitions for ram that I've seen before include "Crash into, maybe for battering" , "what comes after fish" , "Strike violently" , "Pound" , "Computer memory of a sheep?" .)
