Self-described "fermentation revivalist" Sandor Katz says "the creative space" between fresh and rotten is the root of most of humanity's prized delicacies. His new book, The Art of Fermentation, explores the ancient culinary art form.
"If you walk into a gourmet food store and start thinking about the nature of the foods that we elevate on the gourmet pedestal, almost all of them are the products of fermentation," he tells Fresh Air's Terry Gross. "Fermentation creates strong flavors.
But they're not always flavors that everybody can agree on."
