Cast Iron Skillet Seasoning

Cast iron skillet sitting on my stove is the only piece of cookware that improves with use rather than degrading. Seasoning, a thin layer of polymerized oil baked onto the surface, builds up over months of cooking into a natural nonstick coating that no Teflon pan can match in durability or flavor. My grandmother's, the seasoning on it has been accumulating for probably 40 years, the surface glossy and black and so slick that eggs slide around without any oil added. Maintenance ritual is simple, cook, wipe with a cloth while hot, add a thin coat of oil, never use soap. That discipline of care creates a relationship with the object that disposable cookware doesn't invite. Weight is significant, about 8 pounds for a 12-inch pan, and picking it up with one hand requires forearm strength that cooking with it has actually developed. Heat distribution is different from stainless steel, cast iron holds temperature so steadily that a steak sears evenly without hot spots and the thermal mass means the pan doesn't cool down when cold food hits it. Also the original heirloom kitchen object, cast iron pans from the 1800s are still in daily use. Cooking with the same pan my grandmother used connects me to a lineage of meals that the pan participated in. Community around cast iron is committed, people sharing reseasoning techniques and restoration projects online with the intensity of car enthusiasts. That devotion to maintaining a simple iron disc says a lot about the satisfaction of owning 1 well-made thing for life.
