Marcella Hazan didn't just teach Italian cooking — she changed the way America eats. A trained scientist who never cooked professionally until immigrating to New York, Hazan became a culinary icon through self-taught cooking classes, a column for The New York Times, and bestselling books including The Classic Italian Cook Book. Featuring interviews with Jacques Pépin, Lidia Bastianich, and her husband and writing partner Victor Hazan, the film reveals the exacting, fearless woman behind the recipes that reshaped home kitchens across America.
