6.2  The simmering zones

The simmering zones on the hob can be used for simmering food until it is done and
for keeping food warm.
As from setting 8, this part of the glass ceramic hob heats up so intensely that additional
simmering is possible.

Example of an application

Menu:

Beef soup
Roast pork
Vegetables
Potatoes

Cook the beef soup and the roast pork on the two front cooking zones until the food is
3/4 done. Then slide both pans to the simmering zones and cook the vegetables and
the potatoes on the front cooking zones.

If the cooking zones are loaded in this way, all the food will be cooked until it is done. 

6.3  Notes on the use of the right saucepans

Using the right saucepans will help you to 
reduce cooking times and save energy.

Only use saucepans with a smooth and even 
base.

Saucepan and pan bases must contract inwards slightly in the cold condition as they
expand when hot and then rest on the cooking zone. This is the best way for the heat
to be transferred. 

The optimum base thickness is 2 – 3 mm for steel enamel and 4 – 6 mm for stainless
steel with a sandwich bottom.

The saucepan bases must be clean and dry in order to avoid scratches on the glass
ceramic hob.

Do not use saucepans made of cast iron or saucepans with electrographic bases.
Never use aluminium dishes or plastic vessels!

Avoid saucepans boiling dry.
