Is it okay to wash mushrooms?
To wash or not to wash? Though the conventional wisdom says not to wash mushrooms, we side with Jacques Pepin, Harold McGee and Alton Brown, all of whom say that washing leads to neither mushy mushrooms nor lost flavor. Most of the time though, you'll be okay just brushing over dark spots with a damp paper towel. However you decide to clean your mushrooms, wait and clean them just before you need them.
