Note more money for cook (6)
I believe the answer is:
braise
'for cook' is the definition.
(braising is a kind of cooking)
'note more money' is the wordplay.
'note' becomes 'b' (musical note).
'more money' becomes 'raise' (as in an increase in wages at work).
'b'+'raise'='BRAISE'
(Other definitions for braise that I've seen before include "Fry then stew, eg, steak" , "Cook or stew slowly" , "Fry then stew (meat)" , "Heat slowly" , "Rabies (anag.)" .)
