One of the authors is the head recipe tester for Chocolatier Magazine, and the recipes in this cookbook are similar to the ones you will find therein; it has the same advantages and drawbacks. Specifically, it is a productive resource for the professional or the veteran amateur pastry chef. The recipes are probably too ambitious and the instructions too vague for the average home cook.
The introductory chapter is a mixed bag. The essays on types of chocolate, tempering, and tools are exemplary. On the other hand, the sections on non-chocolate ingredients and various techniques and procedures (such as whipping egg whites or proper batter folding technique) are virtually absent. It also has the obligatory and disposable information on chocolate history and manufacturing.
Interestingly, the book has three main sections, one each for milk, dark, and white chocolates. Here, you will find recipes mainly for cakes, cookies, and confections. In a rare moment of honesty, the authors admit that milk chocolate has such a weak chocolate flavor that it is easily overwhelmed in a recipe. There are slightly more than 50 recipes, and they are all listed and cross referenced in the table of contents.
The recipes themselves are problematic. The main error here is the listing of ingredients in volume (e.g. cups) with no equivalents given in weight. This is a major problem for professionals who will try to multiply the recipes, and also for any recipe that has flour. They all list prep times, but never the cooling or baking times. Many of the recipes are complicated affairs that have several components. The result is a recipe that takes up several pages, but even so the instructions are quite scant; they are sufficient for professionals, but not detailed enough for the inexperienced. There is no advice on how to coordinate the execution of a complex recipe with several different sub-recipes. Each recipe has a picture, which is a good thing, but the presentation and decorating instructions in the recipes sometimes do not match the food styling in the photos. These problems will not be a hindrance for the experienced, but will be major trouble for the average home cook.
The most interesting feature of this book is the variety of truffle recipes. Each one has detailed instructions from A to Z for using the fancy, plastic truffle molds that can be bought on the internet in a bewildering array of different types and shapes. There is also a recipe for using chocolate transfer sheets.
