Cookware

IMPORTANT: Do not leave empty cookware on a hot surface
cooking area, element or surface burner.
Ideal cookware should have a flat bottom, straight sides and a well-
fitting lid, and the material should be of medium-to-heavy
thickness.
Rough finishes may scratch the cooktop or coils. Aluminum and
copper may be used as a core or base in cookware. However,
when used as a base they can leave permanent marks on the
surfaces.
Cookware material is a factor in how quickly and evenly heat is
transferred, which affects cooking results. A nonstick finish has the
same characteristics as its base material. For example, aluminum
cookware with a nonstick finish will take on the properties of
aluminum.
Cookware with nonstick surfaces should not be used under the
broiler.
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 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.
May leave aluminum residues, which
may be diminished if cleaned
immediately after cooking.
Cast iron Heats slowly and evenly.
Good for browning and frying.
Maintains heat for slow cooking.
Rough edges or burrs may scratch the
cooktop.
Ceramic or Follow manufacturer's instructions.
Ceramic glass

settings.
May scratch the cooktop.

Stainless steel
Use 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 or the coil element.
Cookware should not extend more than ½" (1.3 cm) beyond the
surface cooking area or element.

Home Canning

When canning for long periods, alternate the use of surface
burners between batches. This allows time for the most recently
used areas to cool.
Center the canner on the grate above the burner.
Do not place canner on 2 surface burners at the same time.
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.
