Baked pastry dish (3)
I believe the answer is:
pie
'baked pastry dish' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for pie that I've seen before include "Dish baked in pastry-lined pan" , "something with custard, say" , "what to cook for dinner?" , "Small, former coin of India" , "Filled pastry" .)
