What is the history of the egg?"Eggs existed long before chickens," according to On Food and Cooking: The Science and Lore of the Kitchen by Harold McGee. "The first eggs were released, fertilized, and hatched in the ocean. Around 250 million years ago, the earliest fully land-dwelling animals, the reptiles, developed a self-contained egg with a tough, leathery skin that prevented fatal water loss. The eggs of birds, animals that arose some 100 million years later, are a refined version of this reproductive adaptation to life on land. Eggs, then, are millions of years older than birds. Gallus domesticus, the chicken more or less as we know it, is only a scant 4 or 5 thousand years old."
Now, 20 years later, McGee has taken his slightly outdated volume and turned it into a stunning masterpiece that combines science, linguistics, history, poetry and, of course, gastronomy. He dances from the spicy flavor of Hawaiian seaweed to the scientific method of creating no-stir peanut butter, quoting Chinese poet Shu Xi and biblical proverbs along the way. McGee's conversational style—rich with exclamation points and everyday examples—allows him to explain complex chemical reactions, like caramelization, without dumbing them down. His book will also be hailed as groundbreaking in its breakdown of taste and flavor. Though several cookbooks have begun to answer the questions of why certain foods go well together, McGee draws on recent agricultural research, neuroscience reviews and chemical publications to chart the different flavor chemicals in herbs and spices, fruits and vegetables.
