Put 2 tablespoons of butter in a deep saucepan, and when melted stir into it, with a flat-ended wooden spoon, 2 tablespoons of flour and let brown, then add 2 tablespoons of vinegar and use 2 cups of boiling water or vegetable stock in making this into a smooth sauce. Add 1/2 an onion, sliced, 2 cloves, 2 allspice, a piece of thin lemon peel, 1 tablespoon of lemon juice, and let cook very slowly, stirring for ten minutes. Then add more vegetable stock or boiling water to make a thin sauce and strain it; return to the fire and add 5 or 6 parboiled thinly sliced potatoes, 2 tablespoons of capers, and let cook slowly for fifteen minutes, stirring frequently; then pour into the saucepan 1/2 cup of cream (sour preferred), and serve in a deep, hot dish. SAVOURY POTATO CAKES Chop 6 cold boiled potatoes, and crush with a potato masher (or use cold mashed potato); add to them 1 tablespoon of mixed herbs, 1 teaspoon of chopped onions, pepper, salt, 1 tablespoon of melted butter, and 1 beaten egg; mould into flat cakes, and put in a frying pan containing 1 tablespoon of melted butter; brown, and turn with a pancake turner to brown the other side. POTATO HASH Put 8 cold boiled potatoes and 2 medium-sized onions in a chopping bowl and chop them fine. Melt 1 tablespoon of butter in a large frying pan, place the potatoes and onion in it, and smooth the top even with a fork. Season well with salt and pepper and put over a moderately hot fire, shaking the pan vigorously from time to time to keep the hash from burning. If it is shaken instead of being stirred it will brown well on the bottom. Turn out onto a hot serving dish, with the browned part on top, and sprinkle with salt and pepper. POTATO OMELET Butter a frying pan with 1 teaspoon of butter, and cover the bottom of the pan with sliced cold boiled potatoes laid flat; let these fry a few moments, then pour over them 2 well-beaten eggs and 1 tablespoon of chopped parsley or chives, season well with salt and pepper, and turn from the pan when browned. CURRIED POTATOES Chop 1 good-sized onion very fine, and fry in 2 tablespoons of butter until transparent and cooked, but not brown; then remove most of the onion with a strainer, pressing the juice from it into the butter, and put in 4 or 5 sliced cold boiled potatoes; sprinkle some curry powder and salt and pepper over them and fry, turning them frequently until done. The amount of curry can vary from 1 to 2 teaspoons. POTATO FRICASSEE Put in a saucepan 1 generous tablespoon of butter and 1 cup of milk; when hot add some cold potatoes cut in dice, season with pepper, salt, and a few drops of onion juice. Let them get thoroughly hot, then add the beaten yolks of 2 eggs, stir constantly until thick. Great care must be taken not to let it cook too long or the sauce will curdle. Add a little chopped parsley before serving. POTATOES RENNEQUIN Boil 6 potatoes, peel them, and let them dry in a warm place on the stove.
