I have seen a lot of posts refer to a heating core or a flower nail to put in the center of larger cakes. Can anyone tell me what one is and how it is used. thanks.
A heating core or flower nail is put in the center of a cake pan to conduct the heat to the cake's center and ensure even baking.
The flower nail is actually meant to be used in making flowers. Placed upside down (after greasing/spraying) it works well for this purpose.
A core is usually a cone-shaped aluminum item used for the same reason. I like the nail as it doesn't leave a 'hole.' HTH
