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