At first I thought to myself yet "that can fold but never"! But I was taught. But it can and yes, it does.
The form should be well greased (preferably with Spray), so that nothing sticks. The first time I've additionally ausgemehlt the shape that I was no longer going to do. Through the flour, the slit of the baking mold has (so to speak of the slot from the heart) was added and the heart shape came at the end of the cake is no longer 100% over.
The filling should not be too liquid, otherwise there is little mess when assembling the cake. ;)
Or you are the more fluid filling in the lower part and in the upper part which must be turned over is one slightly firmer filling.
Anyway, I love my HERZallerliebste cake pan!
