Melt the butter in a stewpan and fry in it the carrots and potatoes, sliced very thin, for about ten minutes, or until they begin to brown. Scald the tomatoes by pouring boiling water over them, remove the skins, slice them, and place in the stewpan with a sprinkle each of salt, pepper, sweet herbs, and the shalot, very finely minced. Stew altogether gently for about half an hour (the juice from the tomatoes with the butter makes sufficient liquor), and when thoroughly cooked, pour into a shallow pie-dish. Break the eggs and separate yolks from whites, beat the former and stir in the bread crumbs, with which have been mixed a pinch of salt and pepper; then beat the whites to a stiff froth, mix in with the yolks, stir well altogether and place over the stew in the form of crust, and bake a quarter of an hour in a very brisk oven. Serve hot or cold.
