Mayonnaise, Hollandaise, Bernaise 'edited by' Justine Harding et al.
I bought this online, unseen, while researching whether or not to write my own book on the topic. This book contains a compilation of sauce recipes from previously published sources owned by the publisher. There is no author given for any recipe, they just credit the editors of the source cookbooks. The 200+ recipes given include gravies, pestos, marinara sauces and fruit coulis. Only 17 of the recipes are for a mayonnaise, hollandaise or bernaise and those recipes are just the bare-bones classics taken/stolen from Escoffier, Mrs. Beeton, and other classic sources. If you own any decent comprehensive cookbook like Joy, Fannie Farmer, Escoffier, Julia's Mastering the Art, etc. you already have these recipes and far, far more.
The binding is hardback, and that's the only nice thing I can say about this book. Amazon.com has copies for $2.45 and I am warning you not to waste your money on it, you will regret it.
