<p> and it will be kind to you.</p> <p> Sheryl Canter has <a href="http://sherylcanter.com/wordpress/2010/01/a-science-based-technique-for-seasoning-cast-iron/">a very specific technique for seasoning cast iron cookware</a> that is supposed to produce amazing results. Like all the best techniques, it&#39;s grounded in science rather than hearsay.</p> <p> But don&#39;t take her word for it–Americas Test Kitchen tried her technique, and found that after treating a cast-iron skillet based on her technique, you could send it through a commercial wash cycle–with degreasing agent–and the finish was undamaged.</p>
