Did not finish.
I enjoy Good Eats, I generally enjoy Brown's perspective on cooking, and I definitely agree that knowing the foundation of cooking will make you a better cook. This book, however, is not for me.
Too many pages had text discussing one thing, sidebars discussing something else, and drawings demonstrating a third. Like learning food science from an unmedicated 5 year old with ADHD. The drawings were also too stylized, not as basic and clear as the drawings in Brown's other books. The fact that his other books are sketches "by Alton Brown" and this book are illustrations by (6) other people "based on sketches by Alton Brown" is probably why it ended up looking like they were trying too hard to be pretty and slightly retro and eye-catching. Sorry, I don't need eye-catching, I need basic and clear, with no off-set colour.
Additionally, some visual aids that would work well in a video format (ie, on Good Eats) just do not work in a written/drawn form. The Lucy Model, for example, in which Lucy and Ethel are food and candies on a conveyor belt are the temperature of water, left me understanding convection less well than I did before I started reading the book.
Overall, the book was frustrating and I choose to stop spending my time on it. It's like the modern American inability to concentrate (short attention span) in book form. There are almost no pages that can just be read, nearly every page requires reading a bit, then down to the footnotes, then over to the graphic, then the other direction to the sidebar box, then follow the arrow to the extra note, then to the other sidebar for the last sidebar box, then back to the text, which is full of bullet points and bolded phrases and subheadings.
