The origin of the name is uncertain. It may be named afterPhilippe, duc de Mornay (1549–1623), the French diplomat and writer, but a cheese sauce during this time would have to have been based on avelouté sauce because béchamel had not yet been developed,[3] so the cheese sauce that the Duke would have known was different from the contemporary version.[4]
Sauce Mornay does not appear inLe cuisinier Royal, 10th edition, 1820, perhaps becausesauce Mornay is not older than the seminal Parisian restaurantLe Grand Véfour, wheresauce Mornay was introduced.[3]
Mornay sauce is a smooth sauce made frombéchamel sauce (butter, flour, milk), grated cheese, salt, and pepper, and often enriched with egg yolk.[5][6] When used for fish, the sauce is generally thinned with fish broth.[7][8] The cheese may be Parmesan and Gruyère,[6][9][8] Parmesan alone,[5] Gruyère alone,[10] or various other cheeses.
