Portabella mushrooms are large in size and have a rounded, flat cap. The smooth cap ranges from dark brown to tan and is firm, thick, and spongy. Underneath the cap, there are dark brown, fleshy gills, a small ring from the cotton-like veil, and the stem is fibrous, white, and dense. When cooked, Portabella mushrooms have a memorable chewy and meaty texture and a smoky, earthy flavor. These mushrooms are 4/5" sliced.
