wellinghall's post reminded me that I've been meaning to point people to the cakewrecks blog for a while. In particular, the blog also does a weekly series on cakes that get it spectacularly right. You can tell that the author is a fantasy fan, because the first few are on
dragons and unicorns (the dragons are amazing),
castles and fairies (least interesting set so far),
Lord of the Rings, and
baby dragons.
