Home Canning
When canning for long periods, alternate the use of surface
cooking areas, elements or surface burners between batches.
This allows time for the most recently used areas to cool.
■ Center the canner on the grate or largest surface cooking
area or element. Canners should not extend more than 1 in.
(2.5 cm) outside the cooking area.
■ Do not place canner on two surface cooking areas, elements
or surface burners at the same time.
■ On ceramic glass models, only use flat-bottomed canners.
■ On coil element models, the installation of a Canning Unit Kit
is recommended. If not installed, the life of the coil element
will be shortened. See “Assistance or Service” for ordering
instructions.
■ For more information, contact your local U.S. Government
Agricultural Department Extension Office. In Canada, contact
Agriculture Canada. Companies who manufacture home
canning products can also offer assistance.
Cookware
IMPORTANT: Never leave empty cookware on a hot surface
cooking area, element or surface burner.
Ideal cookware should have a flat bottom, straight sides, a well-
fitting lid and the material should be of medium-to-heavy
thickness.
Cookware material is a factor in how quickly and evenly heat is
transferred, which affects cooking results. A non-stick finish has
the same characteristics as its base material. For example,
aluminum cookware with a non-stick finish will take on the
properties of aluminum.
Use the following chart as a guide for cookware material
characteristics.
COOKWARE CHARACTERISTICS
*Aluminum
■ Heats quickly and evenly.
■ Suitable for all types of cooking.
■ Medium or heavy thickness is best for
most cooking tasks.
Cast iron
■ Heats slowly and evenly.
■ Good for browning and frying.
■ Maintains heat for slow cooking.
■ Rough surfaces may scratch cooktop.
Ceramic or
Ceramic glass
■ Follow manufacturer’s instructions.
■ Rough surfaces may scratch cooktop.
■ Heats slowly, but unevenly.
■ Ideal results on low to medium heat
settings.
*Copper
■ Heats very quickly and evenly.
Earthenware
■ Follow manufacturer’s instructions.
■ Use on low heat settings.
Porcelain
enamel-on-
steel or cast
iron
■ See stainless steel or cast iron.
Stainless steel
■ Heats quickly, but unevenly.
■ A core or base of aluminum or copper
on stainless steel provides even
heating.
*Aluminum and copper may be used as a core or base in
cookware. When used as a base it can leave permanent marks
on the cooktop or grates.
