How to Season an Iron Kettle

From the The Successful Housekeeper, 1895: "The best way to prepare a new iron kettle for use is to fill it with clean potato peelings, boil them for an hour or more, then wash the kettle with hot water, wipe it dry and rub it with a little lard; repeat the rubbing for half an dozen times after using. In this way you will prevent rust, and all the annoyances liable to occur in the use of a new kettle."
