A sauce is a thick, liquid preparation eaten with some foods in order to give additional flavor and nourishment. It is thickened by the addition of some ingredients (liasions) such as roux, eggs, butter and farinaceous products. Its use is to supply additional richness; or to add some nutriment to a dish by its food value, and sometimes to counteract the richness of some food and to add piquancy of flavor.Simple sauces may be divided into the following groups:
1.    Those made with a roux, the simple ones being household, white, and brown sauces. There are also some superior sauces made with a roux.
2.    Those thickened with cornflour, flour, custard powder, rice flour, etc
3.    Those made with an egg base, eg, custard sauces.
4.    Cold sauces, eg mayonnaise
5.    Unclassified sauces, eg meat sauce, bread sauce, jam sauce.

HOUSEHOLD SAUCES
Plain white sauce

The ingredients: Butter or margarine and liquid suitable for the food with which the sauce is served. For savoury sauces meat, fish, or vegetable stock and milk are used in equal quantities. For sweet sauces, milk and water. The roux is equal quantities of flour and fat cooked together, the proportion of liquid varying with the purpose for which the sauce is intended.
    There are three types of white sauce: coating sauce, pouring sauce and binding sauce or panada.
Basic proportions

Pouring sauce            coating sauce            panada
15g flour            25g flour            50g flour
15g fat                25g fat                50g fat
250ml liquid            250ml liquid            250ml liquid
Seasoning             Seasoning            Seasoning

1.    Melt the fat in a saucepan
2.    Add the flour. Mix smoothly with a wooden spoon and cook over a gentle heat for 3-4 minutes stirring all the time without allowing the roux to brown.
3.    Remove from the heat and add the liquid, a little at a time, to the roux, stirring all the time until the mixture is smooth and creamy. A lumpy sauce will result if the liquid is not added gradually
4.    Add the remaining liquid and mix thoroughly.
5.    Return to the heat, bring to the boil, stirring all the time to prevent lumps of forming
6.    Continue boiling and stirring for 4-5 minutes to cook the flour thoroughly, otherwise the flavor will be raw, the sauce will not thicken properly, the consistency will be incorrect and the appearance  dull instead of glossy.
7.    Season well but carefully
8.    If the sauce is too thick add a little liquid, bring to the boil and boil, stirring all the time. If too thin, reduce by boiling rapidly, stirring all the time, as it is apt to burn at this stage.
If the sauce is allowed to stand over a gentle heat once it is made, dextrinization takes place and the sauce becomes thin. To save time at the last minute, make the roux and add the liquid. Allow this to stand and finish cokig immediately before serving.
A skin forms on the top if the sauce is cooked and allowed to stand. To prevent this, cover the surface closely with a piece of greaseproof paper dipped in cold water and place the lid on the saucepan. To re-heat it, stir vigorously to prevent lumps from forming and then heat gently.
