WHAT ARE MICROWAVES?
SUITABLE OVENWARE
Microwaves are generated in the microwave oven
by a magnetron and cause the water molecules in
the food to oscillate.
Heat is generated by the friction which is caused,
with the result that the food is thawed, heated or
cooked.
GLASS AND CERAMIC GLASS
Heat-resistant glass utensils are very
suitable. The cooking process can be
observed from all sides. They must
not, however, contain any metal (e.g.
lead crystal), nor have a metallic overlay (e.g. gold
edge, cobalt blue finish).
CERAMICS
Generally very suitable. Ceramics must be glazed,
since with unglazed ceramics moisture can get into
the ceramic. Moisture causes the material to heat up
and may make it shatter. If you are not certain
whether your utensil is suitable for the microwave,
carry out the utensil suitability test.
PORCELAIN
Very suitable. Ensure that the porcelain does not have
a gold or silver overlay and that it does not contain
any metal.
PLASTIC AND PAPER UTENSILS
Heat resistant plastic utensils which are suitable for
use in the microwave can be used to thaw, heat and
cook food. Follow the manufacturer's
recommendations.
Heat-resistant paper made for use in a microwave
oven is also suitable. Follow the manufacturer's
recommendations.
MICROWAVE FOIL
This, or heat-resistant foil, is very suitable for covering
or wrapping. Please follow the manufacturer's
recommendations.
ROASTING BAGS
Can be used in a microwave oven. Metal clips are
not suitable for fastening them since the roasting bag
foil might melt. Fasten the roasting bag with string and
pierce it several times with a fork. Non heat-resistant
food wraps are not recommended for use in a
microwave oven.
BROWNING DISH
A special microwave dish made from ceramic glass with
a metal alloy base, which allows food to be browned.
When using the browning dish a suitable insulator,
e.g. a porcelain plate, must be placed between the
turntable and the browning dish. Be careful to adhere
exactly to the pre-heating time given in the
manufacturer's instructions. Excessive pre-heating can
damage the turntable and the turntable stand or can
trigger the safety-device which will switch off the oven.
METAL
Generally speaking, metal should not be used, since
microwaves do not pass through metal and therefore
cannot reach the food. There are, however,
exceptions: small strips of aluminium foil may be used
to cover certain parts of the food, so that these do not
thaw too quickly or begin to cook (e.g. chicken
wings).Small metal skewers and aluminium containers
(e.g. of ready- cooked meals) can be used. They must,
however, be small in relation to the food, e.g.
aluminium containers must be at least
2/
3
to
3/
4
filled
with food. It is recommended that you transfer the
food into a dish suitable for use in the microwave.
When using aluminium containers or other metal
utensils there must be a gap of approx. 2 cms between
them and the walls of the cooking area, otherwise the
walls could be damaged by possible arcing.
NO UTENSIL SHOULD HAVE A METAL
OVERLAY
metal parts such as screws, bands or handles.
UTENSIL SUITABILITY TEST
If you are not sure whether your utensil is suitable for
use in your microwave oven, carry
out the following test: Place the utensil
into the oven. Place a glass container
filled with 150 ml of water on or next
to the utensil. Switch on the oven at 800 W power
for 1 to 2 minutes. If the utensil stays cool or just
warm to the touch, it is suitable. Do not use this test
on a plastic utensil. It could melt.
