This book is as close as we'll ever get to a master compendium of humankind's knowledge and practices of fermentation. Katz has wandered the globe, documenting rapidly-vanishing ancient recipes, traditions, and methods of fermenting everything from vegetables and fruits to meat and dairy products. I could never live without this cookbook. Fermentation increases not only the flavor of ingredients, but their nutritional value and bioavailability. While the advent of refrigeration has rendered fermentation unnecessary, because we no longer need to store things at room temperature, our bodies yearn for fermented foods as much as our palates enjoy them. Katz teaches you to make sauerkraut, yogurt, wine, homemade sodas, and a litany of other things your mind has never even dreamed of.
