Reportedly worked flour into dough, as required (6)
I believe the answer is:
needed
'required' is the definition.
(synonyms)
'reportedly worked flour into dough' is the wordplay.
'reportedly' shows a homophone (sound like).
'worked flour into dough' becomes 'kneaded'.
'kneaded' sounds like 'NEEDED'.
'as' acts as a link.
(Other definitions for needed that I've seen before include "'Lacked, required (6)'" , "Obligatory" , "Required, necessary" , "Required something essential" , "Lacked something essential" .)
