Mornay Sauce

Mornay sauce is a classic bechamel sauce with two of our favorite cheeses, Gruyere and Parmesan.  Of course, you can substitute your favorite melting cheese…from Swiss, to Cheddar to Blue or Gorgonzola.  This is the perfect sauce for dipping a wonderfully grilled sandwich…Monte Cristo comes to mind.  I’ve been making this for the Loon and me for many, many years, and it never fails.  Give it a try, it’s not hard…and you’ll be making a French classic.  Que oui!!
