I am a pretty advanced baker - meringue buttercreams don't scare me and tempering chocolate is easy.
I have Elizabeth Falkner's Demolition Desserts, which I'm dying to get into (although I don't have an ice cream maker so I can't make a lot of the things in there).
I just got Gale Gand's Butter Flour Sugar Eggs - it was on my Amazon.com wishlist and a friend got it for me - but, after looking through it, it's really easy (I've made lots of things that she has in there entirely on my own - ex, blueberry hazelnut frangipane tarts) and am going to exchange it for something a little more difficult and inspiring.
SO. What should I get that is sort of hard (not as hard as Demolition Desserts) and will push me a little bit? Also, I need some good standards - what should I get? (I have a ton of other books to exchange so I don't even need to spend money on new books!)
Also, should I get Elisa Strauss' Confetti Cakes?
