This line of Pata Negra pans is made from heavy gauge steel for a durable, long lasting pan that also makes a superior paella. Because it retains more heat, it will cook your paella more evenly. And it will not warp or change shape over high heat over time.
This carbon steel pan is made by a small family company in Valencia. They call it the Pata Negra in a reference to the nickname for Ibérico ham, the highest regarded food in Spain. The quality is superb, with heavy bolted handles.
Because it is carbon steel, with each use it will change color and take on the flavor of each paella you prepare, similar to an Asian wok. After each use it needs to be coated with a light coat of oil to prevent rust. If it does rust, simply scrub it with steel wool and it will be ready to use again.
