Owning a cast iron skillet requires stability. It requires an ability to think in the long term. Can you live up to it? As you will see, this is not the kind of pan you can expect to cook with for a couple years and throw away once it starts to show signs of use. It’s not goddamn Teflon. Your cast iron skillet will outlive you, and your care is important, even crucial. More than anything, you should only have cast iron in your life if you love it. Now ask yourself, are you ready?
I bought a cast iron skillet a couple of years ago and it was one of the best decisions I ever made. We live in a disposable world of planned obsolescence and to have something that you know will outlast you -- well, that's a special feeling. Plus, it's an amazing tool to cook with. But this article is totally right: taking care of the skillet is something you have to take very seriously.
