Although this sauce is traditionally based on hollandaise, any hot emulsified egg sauce can be given added complexity by finishing it with a small amount of beurre noisette. Reserve one-fourth of the whole butter being used to prepare the clarified butter for the base, and cook it gently to the noisette stage. (For a description of how to prepare Beurre Noisette.) Do not add lemon, which, if the butter is still very hot, will cause it immediately to burn. Strain the beurre noisette through a fine chinois and use it to finish the sauce. To prepare
