The Versatile Stock Pot
Although not specifically a canning tool, the versatile stock pot can certainly be used as such. Since they can be utilized in the making of larger batches of soups, stews and sauces, preparing stock, and cooking pasta, bigger cuts of meat, lobster, crabs, and corn on the cob (among other foods), they can also be used for preparing many of these same dishes for canning. Because of their larger size, some will even use their stock pot in the place of a water bath canner.
Versatility you can afford!
