required for glass cooktops.

Observe the Following Points in Canning
Pots that extend beyond i inch
of the surface unit's circle are not
recommended for most surface
cooking. However, when canning
with water-bath or pressure canner,
larger-diameter pots may be used. This
is because boiling water temperatures
(even under pressure) are not harmflll
to the cooktop surfhces surrounding
the surface units.
[] Remember that canning is a
process that generates large
amounts of steam. To avoid burns
fi'om steam or heat, be carefld
when canning.
NOTE:If your house has low voltage,
canning may take longer than expected,
even though directions have been
carefully followed. Theprocess time will
be shortened by:
HO_gEVER, DO NOT USE LARGE
DIAMETER CANNERS OR OTHER
LARGE DIAMETER POTS FOR
FRYING OR BOILING FOODS
OTHER THAN WATER. Most syrup or
sauce mixtures-and all t}_oesof flTing-
cook at temperatures much higher than
boiling water. Such temperatures could
eventually harm the glass cooktop
surfaces.
[]
Be sure the canner fits over the
center of the surface unit. If your
cooktop or its location does not
allow the canner to be centered
on the surface unit, use smaller
diameter pots fBr good canning
results.
Flat-bottomed canners nmst be
used. Do not use canners _4th
flanged or rippled bottoms (often
found in enamelware) because
they don't make enough contact
with the surface units and take a
long time to boil water.
(1) using a pressure canner, and
(2) starting with HOTtap water for fastest
heating of large quantities of water.
CAUTION:

@
Safe canning requires that harmful
microorganisms are destroyed and that
the jars are sealed completely. When
canning foods in a water-bath canner,
a gentle but steady boil must be
maintained for the required time. When
canning foods in a pressure canner, the
pressure must be maintained for the
required time.
After you have adjusted the controls,
it is very important to make sure the
prescribed boil or pressure levels are
maintained for the required time.
Since you must make sure to process
the canningjars for the prescribed time,
with no interruption in processing time,
do not can on any cooktop surface unit
if your canner is not flat.
@
When canning, use recipes and
procedures from reputable
sources. Reliable recipes and
procedures are available from the
manuf_mturer of your canner;
manufacturers of glass jars for
canning, such as Ball and Kerr
brand; and the United States
Department of Agriculture
Extension Set_,ice.
