Bechamel sauce, also known as white sauce. It is a basic ingredient for so many pasta recipes (lasagne, cannelloni just to give you an example). You have two options: buy a good quality brand at the grocery store or make it at home in 10 minutes....only one warning: once you will try the homemade one it will be very very very very difficult to go back to the store bought one :-)Enjoy!!bLet's be in touch:My blog: http://buonapappa.netFacebook Page: https://www.facebook.com/pages/BuonaPappa/107850219338694Google +: https://plus.google.com/u/0/b/106064003575354848706/106064003575354848706/postsInstagram: http://instagram.com/buonapappa
