Prepare the vegetables, cutting the onions and turnips in quarters, and slicing the potatoes and carrots, place them together with the water, salt and half an ounce of butter in a saucepan, and boil for one hour. Scald the tomatoes, remove the skins, quarter and add to the ragoût; simmer for a quarter of an hour longer, then carefully strain away the vegetables and place them in a deep dish; return the liquor to the saucepan, and thicken with the flour and butter made into a paste; stir until the sauce boils and is free from lumps, then pour over the vegetables, and serve hot. Sippets of toast may be added with advantage.
Note. Should the sauce remain lumpy it should be poured over the vegetables through a strainer.
