Observe the Following Points in Canning
Pots that extend beyond 1" (2.5 cm)
of the surf_ce unit's circle are not
recommended for most smf_tce
cooking. Howevm, when canning
with water-bath
or pressure
cannel
larger-diameter pots may be used.
This is because boiling
water
temperatures (even under pressme)
are not lmrmfhl to the cool<top
smf_ces smTounding the surf_ce units.
HOWEVER, DO NOT USE LAR(;E-
DIAMETER CANNERS OR OTHER
LARGE-DIAMETER POTS FOR
FRYING OR BOILING FOODS
OTHER THAN _ATER. Most syrup or
sauce mixtures--and all types of
fi)dng--cook at temperatures much
higher than boiling wamr Such
temperatures could eventually harm
the glass cool<top surfaces.
%
Be sure the canner fits ()vet the
center of the surfi_ce unit. If your
cooktop or its location does not
allow the canner to be centered
on the surf_ce unit, use smaller-
diameter pots for good canning
results.
[] Flat-bottomed canners must be
used. Do not use canners with
flanged or rippled bottoms (often
found in enamelware) because
they don't make enough contact
with the surf_ce units and rake a
long time to boil water
Remember that canning is a
process that generates large
amounts of steam. To avoid bmns
fiom steam or heat, be careflfl
when canning.
NOTE:If your house has low voltage,
canning may take longer than expected,
even though directions have been
carefufly foflowed. Theprocess time will
be shortened bF
(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 canning jars for the prescribed
time, with no interruption in processing
time, do not can on any cooktop
surface unit ff your canner is not flat.
%
When canning, use recipes and
procedures flom reputable
sources. Reliable recipes and
procedures are available fiom the
manufimmrer of yore canner;
manuf_mmrers of glass jars for
canning, such as Ball _': a nd Kerr <':
brand; and the United States
Department of Agriculture
Extension Service.
