Sterilizing or Processing. To sterilize, slowly lower the product in its can, top up, in a kettle or boiler of boiling water; then add water to cover the jars two inches over the top. Bring the water to the boiling-point and keep boiling the length of time given on the time-table for sterilizing the product being canned. A rack in the bottom of the kettle is necessary to keep the cans from resting directly on the bottom, or individual wire holders can be used. Keep the water boiling constantly during the sterilizing process.
