More praise for
What Einstein Told His Cook
I have enjoyed Bob Wolkes column in the Post for years, and his book is as good a read on the science of cooking as there is. Bob is not only well educated, he is a wit and a wonderful, gifted writer who can make anyone understand whats behind the magic that happens in the kitchen. His sound, clever recipes are a welcome bonus.
Mark Bittman, author of How to Cook Everything
The best book on food (not a cookbook) of 2002. Robert Wolkes book is so full of useful information that youll find yourself referring to it again and again. Not only does he have the penetrating mind of a chemistry professor, but Robert Wolke also has a tremendous sense of humor. Besides being packed with all kinds of interesting food science tidbits, this book is just plain funny.

Robert Wolkes terrific book will be invaluable and accessible to every cook. The style is clear, the text is honest, and perhaps best of all the book is fun to read, filled with the whys and hows of the kitchen.
Paula Wolfert, author of Mediterranean Cooking and Mediterranean Grains and Greens
The occasional recipe adds diversity but facts are the books strong point. What Einstein Told His Cook is a scientifically accurate but witty and entertaining study of the chemistry of food and cooking.
Elliot Ketley, Restaurant (UK)
This book should be on the shelf of any serious cooks library. By demystifying the fundamentals of the kitchen, it empowers the cook to navigate recipes with confidence and control.
Lidia Matticchio Bastianich, author of Lidias Italian-American Kitchen and Lidias Italian Table
Wolke [is] a chemist with a preternatural ability to explain complex chemical reactions in simple terms. Whatever the magnitude of the topic, Wolke addresses it with the same understated intelligence and paternal humor.
Tim Carman, Washington City Paper
If you read Bob Wolkes What Einstein Told His Cook , you may have to kick some old wives tales right out of the kitchen. One of the books joys is that some quirks of the kitchen may never have occurred to us. Thats what makes Bob Wolke the science teacher we wished we had when we were stuck with Big Bad Science Snob. Hes not afraid to lunge at a joke to explain a concept when Big Bad would have bored us silly with irrelevant detail.
Suzanne Martinson, Pittsburgh Post-Gazette
Robert L. Wolkes recipes are lab experiments you can eat. Thats what makes reading What Einstein Told His Cook so much fun for the avid home chef who derives as much pleasure from understanding food as eating it.
New York City Record
For the kitchen nerd with a sense of humor. An absorbing read.
Food & Wine (Ireland)
Good science only adds to the enjoyment of the culinary arts. With a sauce of wit and panache, Wolke serves up commonsense answers to every question that a curious cook could ask.
Roald Hoffman, 1981 Nobel Laureate in Chemistry
