If you're the type of cook who needs to know why onions make us cry and gets curious about the molecular structure of melting sugar, then this is definitely the book for you. It has become our #1 reference book for all questions relating to food science, and not a day goes by when we don't end up consulting its pages for one reason or another.
Title & Publisher: On Food and Cooking: The Science and Lore of the Kitchen by Harold McGee. Published by Scribner, 2004.
First Impressions: Thick spine, double-columned pages, tiny print - yup, this is definitely a reference book! The headings and sub-headings are clearly indicated so it's easy to find what you're looking for on the page. The line-drawings and tables sprinkled throughout the book are helpful extensions of the text and useful for quick reference.
The Angle: This book is intended for anyone who's curious about the science behind (or rather, within!) our food and what happens when food cooks. It won't make you a better cook, per se, but we have found that understanding what's happening on a molecular level with our food has translated into more confidence and creativity in the kitchen. Besides the straight-up science information, McGee also covers some of the history of ingredients and the origins of particular foods.
Strengths: On Food and Cooking is simply one of the best and most comprehensive books on food science for the lay person that we've ever come across. McGee doesn't dumb anything down or gloss over details, but you also don't need to worry about having a degree in organic chemistry in order to understand what he's saying. It's not the type of book that you generally read cover to cover (though we know a few people who have!), but instead, we put the index to good use to help us find answers to specific questions.
Recommended? Yes, definitely!
Why? This book answers questions that regular cookbooks tend to gloss over, making it an excellent resource to have in the kitchen. We've also found it quite handy for clearing up food-related debates at dinner parties!

An essential book in any food geek's collection!
I keep this in lab for easy consultation. We think about science all the time and food sometimes.
I almost got it from the library once but then I realized it's not a 2-week-read. It's a book to have on hand. Now I know I need to get it!!

I have a hold on this book at my library right now (wasn't sure if I was ready to buy, because I am broke and every purchase needs to be thoroughly vetted). I would have picked it up today but it's closed... sigh. So looking forward to it though.
Harold McGee is a genius. It's a brilliant book, but one that I've not actually bought yet. It's near the top of the list, though!

This and Mark Bittman's How to Cook Everything are at the top of my to purchase lists for food books.
If you're a fan of "Good Eats" with Alton Brown, you'll notice that it relies heavily on McGee.
I own that book. I love it. I return to it repeatedly. I keep very few books, but this goes in with my small reference book collection that I lug to each new apartment.
