There's a lot to be said for the humble button mushroom. Sure, there are lots of alternatives with exotic looks and funny names, but white buttons are a kitchen staple. They add texture and mild earthy flavor, but almost no calories. They're inexpensive, always available, easy to prepare, and keep well in the refrigerator. Mix them with the exotics or let them stand on their own. They'll never disappoint.
