Cut the rump steaks into thin slices. Quarter the onions and peel off the peel. Heat the clarified butter in a smaller pan and sauté the onions for about a minute, stirring constantly. Add the meat and fry over a high heat for about three minutes, turning frequently. Sprinkle the marjoram on top, pour on the cream, stir and boil open for about a minute. Season with meat stock, salt and pepper. Season to taste with the brandy.
