I just learned of the existence of Dali's cookbook a couple of days ago. It seems to be an odd thing. (Quelle surprise.) There seem to be two kinds of recipes in it, from the excerpts I've read. First, things that sound like they might be tasty but are so ridiculously high maintenance you probably won't put yourself through the trouble. Then there's the "You expect people to eat that?" class of recipe.
I get the feeling that there were many pranks embedded in Dali's life and work. This may be one of them, but who knows for sure?
