Is it possible to process two layers of jars in the canner at one time?
It is possible to reliably process two layers of jars in
a canner at one time. The canner must be tall enough to
allow the two layers to stand upright without touching
the lid of the canner. Place a small wire rack between
the layers so steam or water will circulate around each
jar. Process according to recommended timetables.
