Meet Carbon Steel. It's a perfect hybrid of a cast iron skillet and a stainless steel frying pan. It has a cast iron's heat retention, seasoning, and slick properties and stainless steel's heat control, lightness and cooking speed. French foodies and professional chefs have been using carbon steel for centuries, and we're bringing it to US kitchens. This Made In kit includes the 8", 10", and 12" frying pans in blue carbon steel.
