Hi All! I have a request to make a cake shaped like an Erlenmeyer flask for a scientist theme. Something like this: http://farm3.staticflickr.com/2761/4397741967_e1ee803e21.jpg
The cake will be for about 15-18 servings. How do I go about making this cake? Do I use three or four 6" layers and carve from there? It's hard to estimate servings with so much carving.
Do I do this in 2 "tiers" so its easier to cut, with a board in between the tiers?
Thanks for your help!!
