Before Setting Surface Controls
Cookware material types
The cookware material determines how evenly and quickly
heat is transferred from the surface element to the pan
bottom. The most popular materials available are:
Aluminum - Excellent heat conductor. Some types of food
will cause it to darken (Anodized aluminum cookware
resists staining & pitting).
Copper - Excellent heat conductor but discolors easily.
Stainless - Slow heat conductor with uneven cooking
results. Is durable, easy to clean and resists staining.
Cast iron - A slow heat conductor however will retain heat
very well. Cooks evenly once cooking temperature is
reached.
Porcelaln-enomel on metal - Heating characteristics will
vary depending on base material.
Gloss - Slow heat conductor.
Home Canning
Be sure to read and observe all the following points when
home canning with your appliance. Check with the USDA
(United States Department of Agriculture) website and be
sure to read all the information they have available as well
as follow their recommendations for home canning
procedures.
" Use only quality fiat bottom canners when home canning.
Use a straight-edge to check canner bottom.
* Use only a completely flat bottom canner with no ridges
that radiate from the bottom center when home canning
using a ceramic cooktop.
Make sure the diameter of the canner does not exceed 1
inch beyond the surface element markings or burner. It is
recommended to use smaller diameter canners on
electric coil and ceramic glass cooktops.
" Start with hot tap water to bring water to boil more
quickly.
* Use the highest heat seating when first bringing the water
to a boil. Once boiling is achieved, reduce heat to lowest
possible setting to maintain that boil.
NEVER place or straddle a cooking utensil over 2
different surface cooking areas at the same time. This
will cause uneven heating results and may cause the
ceramic cool<top to fracture.
