What Einstein Told His Cook: Kitchen Science Explained 1st Edition
Purchase options and add-ons
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. 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? 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.) 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? 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? 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? 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. 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? 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? 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?Amazon.com Review
Organized into basic categories like "Sweet Talk" (questions involving sugar), "Fire and Ice" (we learn why water boils and freezers burn, among other things), and "Tools and Technology" (the best kind of frying pan, for example), the book also provides illustrative recipes like Black Raspberry Coffee Cake (to demonstrate how metrics work in recipes) and Bob's Mahogany Game Hens (showing what brining can do). With technical illustrations, tips, and more, the book offers abundant evidence that learning the whys and hows of cooking can help us enjoy the culinary process almost as much as its results. --Arthur Boehm

An example of Wolke’s discussions would be when he speaks of non-stick frying pans, and how they work chemistry-wise. The metal itself of course doesn’t prevent sticking but the spray on coating of PTFE, or polytetrafluoroethylene. PTFE is quite special- on the atomic level it doesn’t want to bond with anything. Of course this means any foreign substance should slide right off, or at least not stick to it. Why does this work? Wolke explains that PTFE is a fluorolymer, meaning the chemical is made up of many smaller structures, in this case containing fluorine and carbon. The way it is arranged fills the outer energy levels of each fluorine, and therefore fluorine wants nothing to do with any other atom, creating the non-stick surface we all know and love.
A second myth Wolke adresses is whether or not lemons yield more juice after being rolled and microwaved. He tests this with a large pool of lemons, and finds that simply squeezing holds up pretty well to those that had been rolled and microwaved. Of course the automatic squeezer claimed the best results. However, Wolke finds that rolling and then microwaving the lemon has the best results for hand squeezing. The rolling breaks the cell walls, followed by the microwaves exciting the water molecules creates this.
Overall, the book was a fun and understandable read, with well organized evidence. Fun topics, such as the mysterious non-stick frying pan, and how to properly juice lemons. Wolke does a good job making a book that is relatable to the audience, yet at the same time is fun to read. I would easily recommend this book to anyone- an interest in chemistry is not required to enjoy this book.
The second chapter on salt is a perfect example of the kind of misunderstandings this book clears up. More than one TV chef (and more than one cookbook author) has spoken at great length about differences in salt, giving one the impression that there is a basic difference between table salt, kosher salt, and sea salt. There is, of course, a difference, but that difference is based almost entirely on the physical differences, akin to the difference between liquid and frozen water. All salt is sodium chloride. By weight, no type of salt gives a saltier result than another. The very small additional differences between, say, kosher salt and sea salt are in the presence of incredibly small quantities minerals in addition to sodium chloride. Even differences in taste may be due to the differences in physical form. I have a sense that these considerations may be just a little too subtle to be worth all this fuss. I'm inclined to agree, until it occurs to me that if someone hears a statement that `kosher salt' is less salty than table salt, they may use this as a reason to use more kosher salt and ignore the evidence of their senses that they are indeed eating a lot of salt. This becomes significant if one must lower their intake of sodium chloride.
This book addresses many such confusions, and addresses them accurately and persuasively. It does this so well that Alton Brown wishes he would have written this book. My suggestion to Alton Brown is that with the lesson of this book, he would be able to do a better job of it.
I may be stepping on an intellectual land mine here since I have not yet read Shirley Corriher's book `Cookwise' so I do not know if she has already been over this territory, but here goes.
I think the definitive book on food science for the masses has not been written yet. This book covers many of the right topics and I found no inaccuracies in the science. But, the book suffers from being a collection of edited columns. Science is about theories explaining facts. For example, a full explanation of salt would involve a discussion of what a salt is, in general, and use this information to show, among other things, why salt is dangerous to people with hypertension and how chemicals other than table salt can influence body fluid volume in hypertensives.
A scientific discussion would extend the notion of salts to what it means to dissolve a salt in water. By doing so, it would clear up the most seriously abused work in cooking explanations. That word is `dissolve' and it's various past, past perfect and pluperfect tenses. Almost every culinary demonstrator on TV and many writers in cookbooks misuse the term dissolve by applying it to the very different operations of creating an emulsion, melting, and creating a colloid.
I think what I am really recommending as some future Alton Brown project is a book that combines physics, chemistry, and physiology to give an UNDERSTANDING of food, cooking, and health. Understanding is the real goal of science, so that one can apply what one knows in one situation to cooking food in other situations. Strange as it may seem, this is an almost perfect characterization of what Herr Brown believes he is doing.
The subtitle of this book, `Kitchen Science Explained' is a perfect representation of how this book is not science itself, but the carrying of science to the `gentiles'. In itself, the title is a redundancy, since science itself is explanation incarnate.
This is a very good book. I found no errors (I was a professional chemist, so I would probably have found really bad errors if there were any) in science. I believe the writing is lucid and entertaining. I believe the author is always intellectually honest in saying when either he does not know the answer or if science in general does not yet have an explanation.
The only point of my ranting is that this is not the ideal book on food science which bridges the gap between the research of Harold McGee and the practical worlds of Alton Brown and Shirley Corriher. A book that comes a lot closer to this goal is McGee's book, `The Curious Cook'.
I recommend this book to anyone with any curiosity about food. Excellent reading even if you don't cook.
What Einstein Told His Cook makes chemistry understandable for all experience levels. For example, I had no idea there were multiple types of sugar until I finished this book. But now I know these types and it honestly affects my daily life. I also did not know the difference between saturated and unsaturated but fully understood the two types after reading this book.
If you have any kitchen or cooking fears then this book is for you. This book proves and disproves many myths that relate directly to our health while still using language that is easy to digest. One of the biggest myths it disproved was that microwaves can cause cancer/are dangerous. It also explained why the green spots on chips aren't dangerous in an understandable way.
What Einstein Told His Cook is a thoughtfully done piece that is a must read for everyone who eats food. All the facts in the book are as true as chemists know being that Wolke is a professor at University of Pittsburgh. If you aren't sure whether the book is for you, put your trust in me; this book is useful for everyone.
