Work, as dough (5)
I believe the answer is:
knead
'work as dough' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for knead that I've seen before include "Somehow work in" , "Massage - naked (anag)" , "Work flour into dough manually" , "Work with finger movements" , "Work (dough/clay)" .)
