With this Tefal mold whose edges are reinforced with metal edges it is possible to unmold just preparation. You press the sides to that preparation comes off without catching on the bottom and also to avoid burning or damaging the cake. It remains soft silicone which allows easy storage when you do not have a lot of storage in your kitchen. It is a product which I pass me. I even plan to complete the range. It passes the furnace but not fail in the microwave due to the presence of iron.
