Béchamel sauce, also known as white sauce, is made from a roux (butter and flour) and milk. It is one of the mother sauces of French cuisine. It is used as the base for other sauces (such as Mornay sauce, which is Béchamel with cheese).
Béchamel is traditionally made by melting a quantity of butter, and adding an equal part of flour to make a roux, which is cooked under gentle heat while stirring with a whisk. As it is a white sauce, care must be taken not to brown the roux. Then heated milk is gradually whisked in, and the sauce is cooked until thickened and smooth. The proportion of roux and milk determines the thickness of the sauce, typically one to three tablespoons each of flour and butter per cup of milk.
One tablespoon each of butter and flour per cup of milk makes a thin, easily pourable sauce. Two tablespoons of each makes a medium thick sauce. Three tablespoons of each makes an extra thick sauce, such as used to fill croquettes or as a soufflé base. Salt and white pepper are added and it is customary in Italy to add a pinch of nutmeg. Optionally a whole or cut onion, studded with one or more whole cloves, and a bay leaf may be simmered with the milk and then strained before adding to the roux.
