FAQs: fresh mushrooms for roasting

How to pick the best mushrooms at the store?

Shopping for mushrooms at the grocery store is easy once you know exactly what to look for! Follow these simple tips for purchasing the best mushrooms:

• Look for mushrooms that are firm with a smooth appearance and no brown spots. Avoid pressing on the mushrooms too hard when checking for firmness or you will bruise them.
• The mushrooms surface should be dry and not damp, nor should they be shriveled and dried out.
• Fresh mushrooms should appear plump and fresh.
• Check the underside of the mushroom cap. If you are looking for a delicate flavor, choose mushrooms with a closed veil and hidden gills under the mushroom cap. For a richer flavor, select mushrooms with an open veil and exposed gills under the cap.

How to store fresh mushrooms?

Once you have selected the perfect mushrooms at the store, it is important they are properly stored.

Fresh mushrooms should be stored unwashed in their original packaging in the refrigerator.

If you purchased loose fresh mushrooms at the store, transfer them to a brown paper bag or storage container with the lid propped open for ventilation before storing them in the refrigerator.

Fresh mushrooms can be stored in the refrigerator for 2-3 days.

Pro-tip #1: Fresh mushrooms need to breathe, so do not place mushrooms in an air-tight container!

Pro-tip #2: Do not clean mushrooms until you are ready to use them!

How to prepare mushrooms for oven roasting?

Once you are ready to cook mushrooms, avoid rinsing them under running water! Soaking fresh mushrooms with water can cause them to turn rubbery and slimy once cooked. To properly clean mushrooms, use a damp paper towel to gently brush off any dirt or debris.

Also, make sure you trim the bottom of the mushroom stems. (For shiitake mushrooms, remove the stems completely as they are tough in texture.)
