Blend, as batter
I believe the answer is:
stir
'blend as batter' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for stir that I've seen before include "Whisk or mix" , "Commotion; agitate" , "where porridge is served" , "Move around and mix thoroughly" , "Thrill" .)
