Portabella Mushrooms

Portabella mushrooms have really made a name for themselves in the past decade. Known for their rich flavor, meaty texture and impressively large caps, they have been widely integrated into culinary delights around the world, having greatest influence on those who enjoy or vegetarian or vegan diet, being served as burgers, fajitas and even “steaks.”

In some regions, the term “Portabella Mushroom” has become interchangeable with “Portobello” and falls under the botanical classification Agaricus bisporus. Other regional names include Agaric cultivé, flat chestnut mushroom, champignon, and the cultivated mushroom.

The portabella mushroom has an impressive nutritional profile. 84 grams has B vitamins, riboflavin, niacin, selenium and pantothenic acid. Portabellas also contain 7% potassium (as much as a small banana).

The portabella mushroom is one of the largest varieties of farm-cultivated mushrooms with a circular cap that matures to approximately 6 inches or 15 centimeters. The firm, spongy, flat cap rests on a thick stem and ranges in color from a deep brown to tan. Under this robust cap are a series of gills, a veil, and a dense white stem. The entire mushroom is edible, so there is no need to peel or scrape out the gills.

Proper storage entails refrigerating the mushrooms in their pre-packaging. When purchased loose, place them in a brown paper bag and refrigerate. Plastic bags and containers tend to accelerate their breakdown.
