I love this book, but it's important to set expectations correctly. Heston Blumenthal is chef at The Fat Duck, consistently rated as one of the best restaurants in the world, known for its innovative cuisine. The title of this book is deceptive. When most people hear "(some chef) at Home" they assume it's home style dishes, probably with the complex ingredients and techniques toned down for the home cook who doesn't have a staff and an unlimited budget. This book is not like that. This is a book for the dedicated home cook, someone who will spend time tracking down hard to find ingredients or spending 4-6 hours cooking a chicken. It does require a lot of equipment, some of which can be rather expensive. Blumenthal does not really encourage you to be creative, to learn from his techniques and flavor profiles and find ways to incorporate them into your own kitchen. In short, it's not really an "at Home" style book.
Title aside, this book is fantastic. It takes home-style dishes, things like roast chicken, meat pies, chili, potato leek soup, and it elevates them. There's a reason roast chicken is such a well-recognized dish, and the recipe in this book will remind you of that reason. Roast potatoes are likewise a simple thing, but truly fantastic when executed properly. That is what this book is about, and it delivers. Those two dishes went over very well at a recent dinner. I haven't had the book long enough to cook all the recipes, but reading them over is pretty thrilling. The titles of dishes may sound plain, but reading through the recipes shows that there can be much more to a chili than just beef, beans, tomatoes and a spice packet. There are a lot of Heston-esque touches, like star anise to increase the umami notes in beefy dishes. If you've read any of this other books, this one will seem familiar. A lot of explanation and science is peppered throughout the recipes, explaining why things work the way they do or how he arrived at a particular dish/ingredient/technique.
Also worth keeping in mind that this is a British book, so you'll see some different dishes and metric measurements - do not be alarmed. For those who have a couple of his other books, you might see some similarities, especially when he gets to his rant about "sealing in the juices".
Overall, this is a very exciting book for someone who knows their way around the kitchen and wants to perfect their techniques and flavors, but it's not for everyone. As someone who has several of his other books, I was a little annoyed with the overlap between books - I'd like to get added value out of my loyalty, not repeat content.
