This recipe is about the Bechamel sauce (White sauce), one of the 5 French mother sauce (Bechamel, veloute, espagnol, hollandaise and tomato). Why is it so called “Mother Sauce”?
Because from it you can create a “Derivative sauce” by adding other ingredients. Such as adding egg yolks and Cheese and you have the famous “Mornay sauce” (my next recipe). Or, add chopped fresh parsley and you have a parsley sauce. Add, mustard and a little cream and you have a mustard sauce. This recipe is a classic.
