This is a wonderful book for the beginner to professional. It takes the time to explain the 5 mother sauces and their derivatives. I enjoyed this book because it took me back to many of the dishes from my childhood. My parents immigrated to the United States in the early 20's from both Northern and Southern Italy. I found familiar recipes in this book from both regions. The author was privileged to work under Escoffier. Thanks Luigi, Chef Ray, Montague, New Jersey
