They should be pierced beforehand so
that steam can escape. This prevents a
build-up of pressure and reduces the
risk of the bag bursting.
Roasting bags
and
tubes
can also be
used. Roasting tubes should be about
40 cm longer and roasting bags about
20 cm longer than the food being
roasted, and carefully tied with string.
Turn the ends over and secure them.
The bag should be pierced according
to the manufacturer's instructions.
Do not use metal clips, plastic clips
containing metal parts or paper ties
containing wire.
There is a danger that they will ignite
when heated.
Wood
Wooden dishes are not suitable.
Moisture contained in the wood
evaporates when exposed to
microwave energy, causing the
wood to dry and crack.
Disposable containers
Only those plastic disposable
containers which are specified by the
manufacturer as suitable for use in a
microwave oven may be used.
Do not leave the oven unattended
when reheating or cooking food in
disposable containers made of
plastic, paper or other inflammable
materials.
Disposable containers are not always
recyclable or bio-degradable.
Testing dishes for their
suitability
If in doubt as to whether glass,
earthenware or porcelain plates or
dishes are suitable for use in a
microwave oven, a simple test can be
performed:
^
Place the item you wish to test in the
centre of the oven, fill a suitable glass
with water and also place this in the
oven.
^
Close the door.
^
Turn the power selector to 900 W.
^
Enter a time of 30 seconds with the
time selector.
^
Press the START button.
At the end of the test, the water in
the glass should be warm and the
dish cool. If the dish is hot the water
cold it would be unwise to use the
dish.
If a crackling noise is heard
accompanied by sparks during the
test, switch the appliance off imme-
diately (press button Stop/C twice).
Any crockery which causes this
reaction is unsuitable for use with
microwave power.
If any doubt exists about the
suitability of containers, please
contact the supplier.
This test cannot be used to check
whether items with hollow knobs or
handles are suitable for use with
microwave power.
