Check for flatness by placing the straight edge of a ruler across
the bottom of the cookware. While you rotate the ruler, no
space or light should be visible between it and the cookware.

Use a flat-bottomed cookware for best cooking results and
energy efficiency. The cookware should be about the same size
as the cooking area outlined on the cooktop. Cookware should
not extend more than
1
/
2
" (1.3 cm) outside the area.
Home Canning
Canning can be performed on a glass smooth top cooking
surface or traditional coil element cooktop. When canning
for long periods, alternate the use of surface cooking areas
or elements between batches. This allows time for the most
recently used areas to cool.
■
Center the canner on the largest surface cooking area or
element. On electric cooktops, canners should not extend
more than
1
/
2
" (1.3 cm) beyond the surface cooking area
or element.
■
Do not place canner on 2 surface cooking areas or elements
at the same time.
■
On ceramic glass models, use only flat-bottomed canners
to avoid damage to the cooktop and elements.
■
For more information, contact your local agricultural
extension office, or refer to published home canning guides.
Companies that manufacture home canning products can
also offer assistance.
