How to Tell if a Portabella Mushroom is Bad?
There are many ways to determine if a portabella mushroom is terrible. These mushrooms belong to the mushroom family and are typically green or white. They are likely toxic unless they’re a variety called “Romulan purple,” they are likely toxic. To clean them, use a damp paper towel to wipe them. However, please don’t make them too wet! When cleaning, scoop out the gills to create an excellent cup for your filling.
Look for signs of deterioration. If the mushroom cap is mushy, it’s likely past its prime.
