Have two dozen of rather good-sized, fine, freshly opened oysters, suppress their liquor, then place them in a saucepan on the fire with half an ounce of very good butter; gently boil them for three minutes, then add half a wineglassful of good old Madeira wine, let the wine reduce one-half. Break into a bowl four fresh egg-yolks, with half a pint of sweet cream, then with the wire whip thoroughly beat them up, and then add it to the oysters, continually and briskly stirring while adding it; let all cook for three minutes, briskly stirring meanwhile. Remove from off the fire, pour into a hot deep dish or tureen and send to the table.
