Cookers (5)
I believe the answer is:
ovens
'cookers' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ovens that I've seen before include "Cooking equipment" , "In which to bake or roast" , "Kilns or stoves" , "Cookers" , "Appliances for baking or roasting" .)
