Potatoes au Maître d’Hôtel.
Slice cold boiled potatoes rather thick. Have ready in a saucepan four or five tablespoonfuls of milk, a good lump of butter, with salt, pepper and minced parsley. Heat quickly; put in the potatoes, and stir until almost boiling. Stir in a little flour, wet with cold milk; cook a moment to thicken it; add the juice of half a lemon, and pour out into a deep dish.
