There are a couple
ways to clean mushrooms, to remove the dirt and grit that
tends to be stuck on the when you purchase them from the grocery
store. If you are only doing a handful, wiping them off with
a damp cloth works well.
If you need to
do a lot, or you were very short on time, there is a quick
and easy way to do it. Simply pop your mushrooms into a colander
and using the spray on your tap, instead of a steady stream,
give the mushrooms a good rinse while swirling around in the
colander to ensure all sides of the mushrooms get washed and
to help remove any loose dirt. Pat dry if you prefer, but
they can be used immediately as it is.
Do note that you
will have about a 15 minute window before the mushrooms start
to turn soggy from the water. So if you need to do it ahead
of time, using the damp cloth method is your best bet.
