We’ve been cooking with cast-iron cookware for centuries! The earliest examples come from China during the Han dynasty, which lasted through 220 AD. While new cooking technologies are constantly emerging, this classic kitchen staple remains as popular as ever. Whether your cast-iron cookware is new, or if you’re lucky enough to have your hands on a true vintage Dutch oven or skillet, there are important rules to follow to ensure the longevity of your cookware. Make sure to keep your cast-iron pieces clean, free of rust, and well seasoned!
