HOW TO SEASON A CAST IRON SKILLET

The skillet you want is at least fifty years old, and right now it is probably sitting on a thrift store shelf or a yard sale table. Your first task is to locate it. Until the 1960s, the final stage in manufacturing cast iron was to machine-polish each pan until the cooking surface was as smooth as glass. New cast iron is sold unpolished, that is, fresh out of the mold, with a texture like pitted Formica. The cast iron companies claim that the new, unpolished skillets are as easy to season and as non-stick as the old, polished ones—but then they would say that.
