For even defrosting and to avoid
overcooking unevenly shaped cuts of
meat, poultry or fish, small pieces of
aluminium foil may be used to mask
wingtips or other thin parts for the
last few minutes of the process.
Make sure that the aluminium foil is
at least 2 cm from the oven walls at
all times. It must not touch the walls.
–
Metal meat skewers or clamps
should only be used if they are very
small in comparison to the size of the
cut of meat.
Glassware
Heat-resistant glass or ceramic glass
are ideal for use in the microwave oven.
Crystal glass contains lead which
could cause the glass to crack.
Glass dishes with a milled rim are
also subject to this risk.
Both are unsuitable.
Porcelain (chinaware)
Porcelain (chinaware) is a suitable ma
-
terial.
Do not use porcelain with gold or sil
-
ver edging or items with hollow
knobs or handles, as insufficient
ventilation may cause pressure.
Earthenware
Decorated earthenware is only suit
-
able if the decoration is beneath an
all-over glaze.
Earthenware can get very hot, and may
crack.
Glazes and colours
Some glazes and colours contain
metal.
This makes them unsuitable for use in a
microwave oven.
Plastics
Plastic containers must only be used
for microwave mode alone.
Plastics must be heat-resistant to a
minimum of 110 °C.
Otherwise the plastic may melt and
fuse with the food.
Special plastic utensils, designed for
use in microwave ovens are available
from good retail outlets.
Melamine is not suitable as it absorbs
energy and heats up.
Disposable containers, such as trays
made from polystyrene, can only be
used for very short timed warming and
reheating of food.
When purchasing new containers,
make sure that they are suitable for use
in a microwave oven.
Plastic boiling bags can be used for
cooking and reheating.
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.
