With her book Salt, Fat, Acid, Heat, Samin Nosrat demystified cooking and made me understand and appreciate flavors in a whole new way. So it came as no surprise when Netflix tapped her for the TV version, which was released on October 11. The artfully rendered four-part series travels the globe, examining how different cultures maximize these four basic culinary elements in their traditional foods. Nosrat has often said that salt is the most essential ingredient.
