Funghi
Portobello
S tier
Portobellos are fully mature brown A. bisporus with open caps, dark gills, and meaty texture for grilling as vegetarian “steaks.” Flavour is the deepest of the common cultivated line. Large caps define the class. Grill whole; roast; stuff. Scrape gills if they muddy a pale sauce. A 1990s-onward menu star still earning plate space.
