Your book's Amazon page features this quote from the author of my book:
"Modernist Cuisine is a landmark contribution to the craft of cooking and our understanding of its underlying principles. Its scale, detail, and eye-opening graphics are unmatched by any other book on the subject. It will be an invaluable resource for anyone with a serious interest in cooking techniques, whether the professional innovations of the last few decades or the long traditions on which they build." --Harold McGee
Based on what I've read of his so far, that is a huge compliment.
Still, though, $500.
