Query: Try a flower nail instead

I have used this heating core many times and it does the job. But recently, I was baking multiple large cake layers and used my Wilton flower nail for some of them.The flower nail worked much better! I put it under the parchment paper, with the point sticking up through the paper. (I always use parchment, greased on both sides, esp for chocolate cakes which are notorious for sticking.)The flower nail didn't deform the cake -- no hole to plug -- and cooked the center just as well. It was easy to remove by flipping the layer onto a wire rack. I also always use insulating strips around the outside of my pans (from Wilton and others) to slow down the outer edges while the middle catches up, resulting in more even tops and more moist outer edges.
