Caring for Cast Iron Cookware
Properly tended, cast iron will not rust nor will it emit the retchsome reek of rancid oil. Why anyone would consider cooking food in a vessel coated with rancid oil, I cannot conceive. Another consequence of the old Troop 451 method is that the iron, predictably, rusts. This time, while we had no rusty iron to remediate (a first, I think!) we did find most of the iron reeking of rancidity. Yuck! The proper care is trivially simple. Clean the vessel in whichever way you wish. Detergent and steel wool will NOT harm a properly seasoned piece of cast iron. This because of the nature of the chemistry involved in seasoning. Like so many real-world processes, this too can be understood by the application of scientific understanding. The root problem is that iron metal and oxygen gas (O2 in the air that we breathe) combine readily in the presence of water. This is an energetically-favorable reaction that occurs spontaneously and water acts as a catalyst in the process. The end product i...
