Michael Ruhlman has enjoyed a long love affair with cooking and food. His explorations of kitchens and the professionals who call them home led Anthony Bourdain to call him "the greatest living writer on the subject of chefs—and on the business of preparing food." But even his vast experience couldn’t have prepared him for the profound shift that has occurred in the chef’s place in society.

Beginning at Per Se, the newest and most expensive of Manhattan’s four-star restaurants, Ruhlman takes readers into some of America’s most illustrious—and most innovative—kitchens. Throughout his travels, he seeks new trends and phenomena, like Las Vegas’s recent elevation to the country’s food Gomorrah with the addition of Picasso and Aureole to the Strip’s already formidable selection, and returns to legendary haunts like The French Laundry, Le Bernardin, and Café Gray to see what’s changed. A dispatch from a new world where chefs are celebrities and culinary school classes are burgeoning, The Reach of a Chef looks at the state of professional cooking in the post-Child, Food Network era. In the end, an audience who loves to talk about, read about, and dine in the finest restaurants in America gets an in-the-trenches look at the professionals whose very life’s work is to feed us.

Why spend time sorting through the millions of cookie recipes available in books, magazines, and on the Internet? Isn't it easier just to remember 1-2-3? That's the ratio of ingredients that always make a basic, delicious cookie dough: 1 part sugar, 2 parts fat, and 3 parts flour. From there, add anything you want -- chocolate, lemon and orange zest, nuts, poppy seeds, cinnamon, cloves, nutmeg, almond extract, or peanut butter, to name a few favorite additions. Replace white sugar with brown for a darker, chewier cookie. Add baking powder and/or eggs for a lighter, airier texture.

RATIOS ARE THE STARTING POINT FROM WHICH A THOUSAND VARIATIONS BEGIN.

Ratios are the simple proportions of one ingredient to another. Biscuit dough is 3 : 1 : 2 -- or 3 parts flour, 1 part fat, and 2 parts liquid. This ratio is the beginning of many variations, and because the biscuit takes sweet and savory flavors with equal grace, you can top it with whipped cream and strawberries or sausage gravy. Vinaigrette is 3 : 1, or 3 parts oil to 1 part vinegar, and is one of the most useful sauces imaginable, giving everything from grilled meats and fish to steamed vegetables or lettuces intense flavor.

Cooking with ratios will unchain you from recipes and set you free. With thirty-three ratios and suggestions for enticing variations, Ratio is the truth ofcooking: basic preparations that teach us how the fundamental ingredients of the kitchen -- water, flour, butter and oils, milk and cream, and eggs -- work. Change the ratio and bread dough becomes pasta dough, cakes become muffins become popovers become crepes.

As the culinary world fills up with overly complicated recipes and never-ending ingredient lists, Michael Ruhlman blasts through the surplus of information and delivers this innovative, straightforward book that cuts to the core of cooking. Ratio provides one of the greatest kitchen lessons there is -- and it makes the cooking easier and more satisfying than ever.
