Toothache looks cool, but $10 an issue for an e-copy seems like it will price itself out of the chef market unless they have tie-ins with Sysco or somebody who will give it to chefs as a perk.
I think t hat the dimensions of the cannelle may be the critical variable. Different ratio of volume to height than a muffin. I believe amazon has cheap silicon cannele trays for less than the price of an issue of Toothache
