from the publisher

Unprecedented in both scope and clarity, La Varenne Pratique is destined to become the essential culinary reference for both novice cook and expert. Written by the founder and director of Paris's prestigious La Varenne cooking school and compiled using La Varenne's extensive resources, the book brings together a practical understanding of cooking techniques, ingredients, and equipment in an unrivaled guide to classic modern cooking.Here in one volume is the answer to every cooking question: how to make a hollandaise sauce (and why egg yolks will only absorb so much oil before the sauce self-destructs); the difference between entrecote and porterhouse; what marinades to use for lamb; which herbs will turn bitter if added at the beginning of a recipe; how to bone a chicken; the roasting times for venison, pheasant, and even squirrel; how to fillet a fiat fish; when to use a bain marie; and much more. Throughout the book, techniques are clearly illustrated with specially commissioned step-by-step photo sequences that set new standards for culinary photography. Readers can actually see what texture a sauce should be, exactly where to make the first cut when boning a Chicken, what the "crust" on a clarifying broth will look like, and what larding a roast really entails.
