Clean Before You Forget What's What
Brush off loose soil and debris with a soft brush or cloth
before you even get home if you can — it's easier to do this
while everything is still separated by where you found it,
rather than facing one big mixed pile later.
A light rinse is fine for most mushrooms, but avoid long soaks
before cooking — many varieties absorb water easily and
become soggy. Save the proper soak for the salt and hot water
baths covered in section 6.2.
