Have you ever wondered why onions make us cry? Do you believe bananas contain more calories as they ripen and get sweeter? This sequel to the best-selling What Einstein Told His Cook continues Robert L. Wolke's investigations into the science behind our foods. In response to ongoing questions from readers of his nationally syndicated Washington Post column, "Food 101," Wolke debunks misconceptions with reliable, commonsense logic. And for exceptionally inquisitive cooks and scientists, he offers "Sidebar Science" features, which dig more deeply into the chemical processes that underlie food and cooking. Above all, What Einstein Kept Under His Hat provides indispensable information that will make readers better shoppers, cooks, and eaters.

Einstein's cook was lucky. But you, too, can have a scientist in your kitchen: Robert L. Wolke.

Do you wish you understood the science of foods, but don't want to plow through dry technical books? What Einstein Told His Cook is like having a scientist at your side to answer your questions in plain, nontechnical terms.

Chemistry professor and syndicated Washington Post food columnist Robert L. Wolke provides over 100 reliable and witty explanations, while debunking misconceptions and helping you to see through confusing advertising and labeling.

o In "Sweet Talk" you will learn that your taste buds don't behave the way you thought they did, that starch is made of sugar, and that raw sugar isn't raw. Did you know that roads have been paved with molasses? Why do cooked foods turn brown? What do we owe to Christopher Columbus's mother-in-law?

o In "The Salt of the Earth" you will learn about the strange salts in your supermarket. Does sea salt really come from the sea? (Don't bet on it.) Why do we salt the water for boiling pasta? And how can you remove excess salt from oversalted soup? (You may be surprised.)

o In "The Fat of the Land" you will learn the difference between a fat and a fatty acid, what makes them saturated or unsaturated, and that nonfat cooking sprays are mostly fat. Why don't the amounts of fats on food labels add up? Why does European butter taste better than ours?

o In "Chemicals in the Kitchen" you will learn what's in your tap water, how baking powder and baking soda differ, and what MSG does to food. What Japanese taste sensation is sweeping this country? Is your balsamic vinegar fake? Why do potato chips have green edges?

o In "Turf and Surf" you will learn why red meat is red, why ground beef may look as if it came from the Old Gray Mare, and how bones contribute to flavor. Want a juicy turkey with smooth gravy? How does one deal with a live clam, oyster, crab, or lobster?

o In "Fire and Ice" you will learn how to buy a range and the difference between charcoal and gas for grilling. Did you know that all the alcohol does not boil off when you cook with wine? How about a surprising way to defrost frozen foods? And yes, hot water can freeze before cold water.

o In "Liquid Refreshment" you will learn about the acids and caffeine in coffee, and why "herb teas" are not teas. Does drinking soda contribute to global warming? Why does champagne foam up? Should you sniff the wine cork? How can you find out how much alcohol there is in your drink?

o In "Those Mysterious Microwaves" you will learn what microwaves do—and don't do—to your food. What makes a container "microwave safe"? Why mustn't you put metal in a microwave oven? How can you keep microwave-heated water from blowing up in your face?

o In "Tools and Technology" you will learn why nothing sticks to nonstick cookware, and what the pressure-cooker manufacturers don't tell you. What's the latest research on juicing limes? Why are "instant read" thermometers so slow? Can you cook with magnetism and light? What does irradiation do to our foods?

This sequel to the best-selling "What Einstein Told His Cook" continues Bob Wolke's investigations into the science behind our foods from the farm or factory to the market, and through the kitchen to the table. In response to ongoing questions from the readers of his nationally syndicated "Washington Post" column, "Food 101," Wolke continues to debunk misconceptions with reliable, commonsense answers. He has also added a new feature for curious cooks and budding scientists, "Sidebar Science," which details the chemical processes that underlie food and cooking. In the same plain language that made the first book a hit with both techies and foodies, Wolke combines the authority, clarity, and wit of a renowned research scientist, writer, and teacher. All those who cook, or for that matter go to the market and eat, will become wiser consumers, better cooks, and happier gastronomes for understanding their food."

"Wolke, longtime professor of chemistry and author of the ?Washington Post ?column Food 101, turns his hand to a Cecil Adams style compendium of questions and answers on food chemistry. Is there really a difference between supermarket and sea salt How is sugar made? Should cooks avoid aluminum pans? Interspersed throughout Wolke's accessible and humorous answers to these and other mysteries are recipes demonstrating scientific principles. There is gravy that avoids lumps and grease; Portuguese Poached Meringue that demonstrates cream of tartar at work; and juicy Salt-Seared Burgers.... With its zest for the truth, this book will help cooks learn how to make more intelligent choices." ?Publishers Weekly?"
