Writer Michael Pollan is the intellectual godfather of the modern good-food movement. His explorations of food and the human experience are unlike any other. Now the man behind The Omnivore’s Dilemma and other works returns with his most conceptual culinary-based book yet. Cooked: A Natural History of Transformation examines the classical elements of fire, water, air and earth with great reporting and recipes to boot. Standing at the intersection of culture and nature, Pollan appears in conversation with the award-winning NPR producer Davia Nelson May 3 at SHED, 25 North St., Healdsburg. 2pm.
