For those who like cooking with cast iron but love the versatility of a clad stainless steel pan, the Viking Blue Carbon Steel 12" wok is the perfect pan. Featuring a 12" size for added versatility, this wok is made of carbon steel, an alloy that is a combination of iron and carbon. Stay-cool cast iron handles securely attach to the pans with heavy duty rivets for confidence in construction and a lifetime of use. Blue carbon steel is also prized for achieving high temperatures quickly without fear of damage occurring to the pan itself. Like cast iron, your blue carbon steel pan will need to be seasoned regularly to maintain its non-stick properties. We recommend using very hot water and dish soap to first scrub the pan, then wipe dry and place it on the burner at low heat to finish drying. Add some oil to the pan and cook over medium heat for about 10 minutes. Then, let the pan cool and wipe with paper towels and your pan is ready for use. For future maintenance, simply rinse the pan with water after use and scrub gently with a soft-bristled brush or sponge if necessary No need for soap. Season with vegetable oil periodically to maintain its smooth cooking surface and non-stick properties. It is not recommended to put these pans into the dishwasher as it will remove the seasoning, reduction the natural non-stick and making the pan more susceptible to rust.
