Want to manipulate dough we hear (4)
I believe the answer is:
need
'want' is the definition.
(I know that want can be written as need)
'manipulate dough we hear' is the wordplay.
'manipulate dough' becomes 'knead' (I've seen this in another clue).
'we hear' indicates a 'sounds like' (homophone) clue.
'knead' sounds like 'NEED'.
'to' acts as a link.
(Other definitions for need that I've seen before include "Lack - demand" , "must have results!" , "Desideratum" , "Penury" , "Lack or require" .)
