Pot maker in production (7)
I believe the answer is:
ramekin
'pot' is the definition.
(I've seen this before)
'maker in production' is the wordplay.
'production' indicates an anagram.
'maker'+'in'='makerin'
'makerin' anagrammed gives 'RAMEKIN'.
(Other definitions for ramekin that I've seen before include "Individual baking dish" , "Small fireproof bowl" , "Small (savoury) dish for one person" , "pot" , "Baking dish for one person" .)
