A complete and comprehensive guide to food preservation, including canning, fermentation and dehydration. Taking Julia Child as her inspiration, Preservation: The Art and Science of Canning, Fermentation and Dehyrdation demystifies the scientific concepts that inform the methods of food preservation in an easy to understand way. More than a cookbook, certified Master Food Preserver Christina Ward has collected and translated both the scientific and experiential information that has long been the sole domain of academic scientists and elite chefs.
