Old Turkish official fed fine cooking (7)
I believe the answer is:
effendi
'old turkish official' is the definition.
(historical title in Turkey)
'fed fine cooking' is the wordplay.
'cooking' is an anagram indicator (cook can mean to falsify or distort).
'fed'+'fine'='fedfine'
'fedfine' with letters rearranged gives 'EFFENDI'.
(Other definitions for effendi that I've seen before include "Turkish address now comparable to 'Mr'" , "Turkish official" , "Levantine gent?" , "Turkish man respectfully" , "Learned Arab" .)
