What is the proper name for a white sauce? Béchamel sauce (Besciamella) is a smooth, white sauce made with just 3 ingredients: flour, milk, and butter. It’s also known as White Sauce or Mother Sauce because many sauces are made with Béchamel as a base, such as Mornay Sauce, which is a somewhat richer version.
