1. Season the steaks on both sides with salt and pepper. Reserve. 2. In a heavy skillet, heat 2 tablespoons of butter until bubbling slightly. Cook the shiitakes over high heat until they begin to brown slightly. Season lightly with salt and pepper. Remove from the pan and keep warm. 3. Carefully pour the Cognac or brandy into the hot skillet and ignite. Let the flame die out naturally. Reduce the Cognac to 2 tablespoons, scraping any loose bits that cling to the bottom of the pan. Return the mushrooms and their juice to the sauce and reduce more if necessary. 4. Grill the steaks on the preheated grill for 3 minutes on each side, or saute them in a very hot skillet with a little oil for 3 minutes on each side, or until the meat is medium rare. Remove from the heat. Yield: 4 servings
