Brandished baking ingredient one dropped (10)
I believe the answer is:
flourished
'brandished' is the definition.
('flourish' can be a synonym of 'brandish')
'baking ingredient one dropped' is the wordplay.
'baking ingredient' becomes 'flour' (eg ingredient in bread).
'one' becomes 'i' (Roman numeral).
'dropped' becomes 'shed' (shedding is a kind of dropping).
'flour'+'i'+'shed'='FLOURISHED'
(Other definitions for flourished that I've seen before include "grew and blossomed" , "Showed off" , "Brandished" , "Did well" , "Was blooming" .)
