Small round baking dish (7)
I believe the answer is:
ramekin
'small round baking dish' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ramekin that I've seen before include "Small (savoury) dish for one person" , "Small fireproof bowl" , "Something to eat from" , "Small ovenproof dish" , "Small baking dish for one portion" .)
