In these they cook a Victorian flower (5)
I believe the answer is:
ovens
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for ovens that I've seen before include "In which to bake or roast" , "means to fire" , "Kitchen appliances" , "Cooking equipment" , "Appliances for baking or roasting" .)
