What is terrific about this book isn't the recipes but the ideas they contain. I will flip through my copy, find a combination of flavors or a new baking technique and will just run with it. If you have begun to improvise with bread baking this book is for you.
As with all the New York Times cookbook, this is a collection of fairly sophisticated gourmet recipes. At forty years old, most cookbooks would be hopelessly outdated and indeed this is showing its age; however, I'd hazard a guess that it's "avant-garde" nature in the early '70s allows it to be slightly above commonplace now.
