Learn More About Portobello Mushrooms
Mushrooms grow quickly, hence the verb, mushroom. Crimini, a small brown umbrella-shaped fungus, will mushroom into the six-inch diameter flat-topped Portobello in only five or six days. Portobello mushrooms are known for their intense earthy flavor.
Like so much in life, mushrooms get better with age. Don’t shy away from shriveled specimens. Although not especially attractive, dryness intensifies the flavor. The mushrooms you bring home should be dry and firm, never slimy.
Once you have your mushrooms home, remove them from the plastic container and plastic wrap. If the gills (underside of the cap) are matted down, give them a whiff. They should have a sweet earthy aroma. If they smell the least bit funky, use your knife to slice away the gills. Place the Portobello mushrooms in a paper bag; if they came in a cardboard container, replace the plastic wrap with paper towel. Either way, refrigerate.
It is perfectly acceptable to simply wipe cultivated mushrooms with paper towel to clean them. Cheesecloth or a brush also work well. If you feel best washing them, give them a quick rinse, running your hands over the surface, then drain quickly. Mushrooms are not sponges — they are already mostly water so exposing them to water is not harmful. Washing does damage the surface, therefore your clean mushrooms should be cooked soon.
The gills you see on the underside of Portobello mushrooms are prominent, and they are stock-piled with browning enzymes. When cooked, the gills will bleed dark juices into your dish which may or may not be desirable. Another cooking pointer: longer cooking gives firmer texture.
Just how did a crimini grow up to be called ‘Portobello?’ I don’t know, but these big browns mushroom when it comes to flavor, texture and versatility.Peggy Crum MA, RD
My inspiration came from a container of spinach in the fridge that needed to be used. I searched my memory bank of recipes and considered my stash. After making several adjustments in the original recipe from Cook's Illustrated, this turned out SO GOOD!
