Briefly - MC is the most important book on the science of cooking since Harold McGee's book On Food and Cooking was published in the 1980's. Nathan Mhyrvold is a former employee of Microsoft, and he has used his millions of $ to buy himself a fancy kitchen filled with the latest toys in the modernist kitchen. He has put together a crack team of research chefs, including some former employees of Heston Blumenthal and Ferran Adria, photographers, etc to produce this beautiful book. It comes in five volumes, with multiple recipes illustrating how modernist techniques can be used to enhance classic recipes, or create entirely new dishes which would be otherwise impossible.
Every page is a delight to read, and some of the photographs truly fill you with childlike wonder. Look at this one:

... and imagine what it would look like stretched over two A4 sized pages in full colour.
Since this is a BBQ forum, it is the section on BBQ which is of special interest to us. When I have time, I will summarize the BBQ section (very quickly: you want a charcoal grill, not gas).
Downsides of this book - most of the recipes are inaccessible without special ingredients or equipment. The recipe for ribeye steak is: sous-vide for 75 minutes, then sear with a MAPP blowtorch. Not any ordinary blowtorch, a MAPP blowtorch. WTF do you buy one of those! With some recipes, you think to yourself - "cool, I can do that!!" and then you read the instruction: "Centrifuge at 33,000rpm for 30 minutes". The recipe for the Modernist Burger includes Liquid Nitrogen.
Some of the recipes seem to be quite superior to the traditional methods - e.g. the duck confit. The Modernist method calls for the duck to be cooked sous-vide - avoiding the need to buy a large quantity of expensive duck fat for a traditional confit. The Mac & Cheese recipe, which I will be doing tonight, avoids the use of Bechamel, instead using Sodium Citrate and Iota Carageenan as an emulsifying agent. Apparently, the flavour release of the modernist emulsifiers is superior to starch.
The book is quite expensive - $650 for the set. But it is well worth it. You won't find it at your local book seller. If you are in Melbourne, suggest you pop down to Books for Cooks in Fitzroy to browse through their store copy.
