Potatoes au Maître d’Hôtel.
Slice cold boiled potatoes a quarter of an inch thick, and put into a saucepan with four or five tablespoonfuls of milk, two or three of butter, pepper, salt, and chopped parsley. Heat quickly, stirring all the time until ready to boil, when stir in a tablespoonful of flour, and two minutes later, the juice of a lemon. Take instantly from the fire so soon as this last ingredient goes in.
