Cut twenty heads of sprue into small pieces, keeping only the tender part, boil them for fifteen minutes, put them into a stewpan, with half an ounce of butter, set them on the fire for three minutes, season with a little pepper, salt, and sugar; when done, put them in the dish you intend to serve it in, break six eggs over, which season as above, put it into the oven until it sets, and serve; in case the oven is not sufficiently hot, place a salamander over the eggs.
