“Patina” is a culinary term for the acquired change in the appearance of the surface of a cooking vessel. With a Professional Steel pan, a patina develops when fat comes into contact with the surface of the metal. The fat penetrates the material and in doing so, transforms it from a dull and dry surface into a slick and supple one.
Nonstick vessels don’t grow and mature with the cook. The surface comes ready from the factory and can only get worse over time. A patina on the other hand is an organic, dyname surface that is sensitive to its surroundings. When a steel pan is seasoned enough to acquire one, the patina becomes virtually nonstick.
