For this purpose take large mushrooms, and be careful to have them freshly gathered. Peel them, score the under side, and cut off the stems. Lay them one by one in an earthen pan, brushing them over with sweet oil or oiled butter, and sprinkling each with a little pepper and salt. Cover them closely, and let them set for about an hour and a half. Then place them on a gridiron over clear hot coals, and broil them on both sides.
