Use for both water bath and steam canning jobs! This heavy-duty aluminum canner comes with a built-in thermometer located on the tempered glass lid with three color-coded elevation settings that helps take the guesswork out of determining processing times based on your altitude. The innovative canning rack allows for both water bath and steam canning, eliminating the need for 2 large canners. The large kettle has a 20 quart liquid capacity and holds 7 quart jars or 8 pint jars. It's safe to use on most newer induction ranges, although caution should be taken to avoid heat build-up.
