I was a bit disappointed after having bought this book.
For me it was the first book on cooking sous-vide, but the only parts I really liked where the introductory pages. They describe some of the principles, results and why's of cooking sous vide. But the recipes are not really inspiring.
Then came the last part of the book: the part with the tables. I liked that very much. It gives you a helpful overview of cooking temperatures and times.
But with a useful introduction and a useful appendix, it does not become a useful book. At least not for this price. Thomas Keller has done so much better in other books.
