Our Mineral B Classic Carbon Steel Fry Pans excel in frying, grilling, and searing, making them ideal for achieving the Maillard reaction, where the caramelization of natural sugars in food helps to seal in flavor and moisture. Composed of 99% iron and 1% carbon, these pans are robust and durable. With no artificial coatings, they develop a natural nonstick surface as they become seasoned over time; the darker they become, the better the nonstick.
