What Are Microwaves; Suitable Ovenware - Sharp R-201W Manual De Instrucciones

WHAT ARE MICROWAVES?

Microwaves are generated in the microwave oven
by a magnetron and cause the water molecules in
the food to oscillate.

SUITABLE OVENWARE

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.
Heat is generated by the friction which is caused,
with the result that the food is thawed, heated or
cooked.
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
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 - 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.
