ABOUT THE BOOK: The Art of Fermentation is the most comprehensive guide to do-it-yourself home fermentation ever published. Sandor Katz presents the concepts and processes behind fermentation in ways that are simple enough to guide a reader through their first experience making sauerkraut or yogurt, and in-depth enough to provide greater understanding and insight for experienced practitioners. While Katz expertly contextualizes fermentation in terms of biological and cultural evolution, health and nutrition, and even economics, this is primarily a compendium of practical information-how the processes work; parameters for safety; techniques for effective preservation; troubleshooting; and more. ABOUT THE DVD: The Fermentation Workshop with Sandor Katz (DVD) offers fermentation beginners and enthusiasts a chance to "sit in" on one of his popular workshops and learn through hands-on demonstration and instruction, accompanied by an interview on the benefits of fermentation, and social implications as it relates to food security. This intimate workshop and interview will prove invaluable both for total beginners and longtime fermentation lovers. The DVD includes: The history of fermentation and culturing Information about microorganisms and pre-digestion Demonstrations on making kefir and sauerkraut Tips on fermentation vessels and storage The truth about food safety (botulism, surface mold, and other fears de-mystified) And more
