Garnish with fresh vegetables if desired. To sweat means to cook in a small amount of fat over low heat. With this method, the ingredients soften without browning, and cook in their own juices. This is a wonderful appetizer to keep your guests amused while you put the finishing touches on the main courses. I would also suggest using these mushrooms as a side dish option on a buffet as they are so beautiful.
Place caps on sheet tray and drizzle extra virgin olive oil to moisten.
Sprinkle with Kosher salt and black pepper. When the caps are done, they will have shrunk quite a bit and be filled with mushroom jus. Set sheet tray aside while you mix stuffing ingredients together. In a small bowl, combine rice, chicken, cheese and chicken stock. Saute diced apple in a small amount of butter and deglaze pan with Madeira wine.
