Fungusheads--that's what a friend of ours calls those of us who become misty-eyed about mushrooms. We can't help it, because as playthings for the senses, mushrooms have it all: a musky fragrance, an exquisitely touchable flesh, an easy compatibility with so many other ingredients, a willing transformation into the state of voluptuousness. A recipe like this is not for fence sitters-it's strictly for fungusheads.
