For baking and roasting (4)
I believe the answer is:
oven
'for baking and roasting' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for oven that I've seen before include "Liquid oxygen; salmon" , "It''s used for baking or roasting" , "kitchen fixture" , "Kitchen range, say" , "Compartment for baking" .)
