THE preparation of a sauce is of as much importance as the preparation of a dish itself and is frequently the supreme test of the cook's skill. Some of the famous cooks of history, like Bechamel, the celebrated chef of Louis XIV, for instance, are remembered chiefly through a sauce of their own invention.

The foundation for almost all of the common sauces is what the French call "roux." This is butter and flour cooked together and thinned with milk, water or other liquid. Under no circumstances should a sauce be thickened by adding a mixture of flour and water, as in this case the flour is seldom well cooked, or by adding flour alone, as this method is certain to cause lumps. The flour should be allowed to cook before the liquid is added.

Brown Sauce

1 tablespoon butter or fat 1 cup stock

1 tablespoon flour Salt and pepper

Brown the flour in the butter, stirring it until smooth; then add the seasoning and the stock, stirring constantly to prevent lumps.

If the sauce is to be served with a roast, use a little of the fat in which the meat was roasted instead of the butter and make the sauce in the roasting pan. For those who like the flavor of onion it is a good plan to roast an onion with the meat, adding it to the sauce.

Onion juice, Worcestershire sauce, tomato catsup or mushroom catsup may be added as flavoring if desired.

Giblet Sauce

If brown sauce is to be served with roast chicken or turkey, boil the giblets three or four hours; mash or chop them, and add them to the sauce.
