For Chewy Edge Lovers
Geometry is coming into play in the cooking industry in an interesting way, as revealed by J.M. (Bellingham WA).
She showed me the new rage for "chewy edge lovers and corner brownie fanatics": The Edge Brownie Pan ($34 at KitchenKrafts.com)...
Though it handles the standard volume of mix for a 9"x9" pan, the "edge" pan shows a good understanding of surface area.
Now, the next step is a "Fractal Brownie Pan," which will have an infinite edge-length but still the same volume!
