Roux is necessary to thicken and give body to sauces. Put one tablespoon of flour and one of butter into a saucepan and cook until the flour has lost any raw taste. Then put the saucepan on the back of the stove and add slowly the stock or milk, one cup for every tablespoon of butter or flour, and stir until smooth. For white sauces take care the flour does not color; for dark sauces let it brown, but take care it does not burn.
Take two tablespoons of sugar (brown or white), one-half a cup of currants, a quarter of a bar of grated chocolate, one tablespoon of chopped candied orange, one of lemon-peel, one of capers, and one cup of vinegar. Mix well together and let soak for two hours; pour it over venison or veal, and simmer for ten minutes.
Take eight ounces of butter, one tablespoon of salt, one of pepper, and two tablespoons of lemon juice. Stir with a wooden spoon over the fire until the butter is half melted, then take it off and continue to stir until it is quite liquid. By taking the butter off the stove before it is all melted it will have a pleasant taste of fresh cream; this is all lost otherwise.
Put two tumblers of white roux and one of chicken jelly into a saucepan, reduce, and add three yolks of eggs mixed with two ounces of butter and the juice of one-half lemon. Before it boils take the saucepan off the fire, and add one tumbler of thick tomato sauce (see Sauces, page 30), strain, and just before serving add one tablespoon of sweet herbs minced fine.
Melt one-half a pound of butter, add a little flour, salt, pepper, and grated nutmeg. Stir until thick, then add one pint of cream, a little chopped parsley, and heat for five minutes.
Put into a saucepan one pound of beef and one-half an onion chopped up with three ounces of lard, some parsley, salt, pepper, one clove, and a very small slice of ham. Fry these over a hot fire for a few moments, moving them continually, and when the onion is browned add four tablespoons of red wine, and four tablespoons of tomato sauce (or tomato paste). When this sauce begins to sputter, add, little by little, some boiling water. Stick a fork into the meat from time to time to allow the juices to escape. Take a little of the sauce in a spoon, and when it looks a good golden color, and there is a sufficient quantity to cover the meat, put the covered saucepan at the back of the stove and allow it to simmer until the meat is thoroughly cooked. Then take out the meat, slice it, prepare macaroni, or any paste you desire, and serve it with the meat, and the sauce poured over all, and the addition of butter and grated cheese.
Chop up fine two ounces of lean ham and a small piece of onion, add a little celery, the stalks of parsley, one clove, one-half tablespoon of pepper, and one-half bay-leaf. Pour over these ingredients a scant one-half cup of vinegar. Cover the saucepan and allow it to boil until it has consumed one-half. Put into another saucepan one-half cup of bouillon (or water in which you have dissolved one tablespoon of extract of beef). Allow it to boil, and then thicken with a teaspoon of potato flour which has been diluted in a little cold water. Drop this, little by little, into the saucepan until you have gained the required thickness for the sauce. Then pour in the boiled vinegar, passing it through cheese-cloth. Mix well together and add a teaspoon of French mustard, some capers, and some chopped-up pickles. Serve hot with meats or tongue. The pepper should predominate in this sauce.
Take some anchovy paste — one tablespoon, two tablespoons of chopped parsley, some capers and chopped pickles, one teaspoon of French mustard, and the yolks of two hard-boiled eggs. Work this all together into a paste, then add three tablespoons of olive-oil and two or three of vinegar and a pinch of salt and pepper. This sauce is good with both meat and fish.
