Containers to use
When unsure that a cooking container
is suitable for use in your microwave,
check by the following test:
1. Fill a microwave safe measuring jug
with 300ml (
1
⁄
2
pt) cold water.
2. Place it on the turntable alongside
the dish to be tested. If the dish you
are testing is a large dish, then
stand the measuring jug on top of
the empty dish.
3. Heat on HIGH power for
1 minute.
Result
If the dish is suitable for microwaving, it
will remain cool, whilst the water in the
jug will begin to feel warm. If the testing
dish feels warm, do not use as it is
obviously absorbing microwave energy.
N.B. This test does not apply to plastic
or metal based containers e.g. Le
Creuset
®
style dishes, which should not
be used as they are cast iron covered
with enamel.
OVEN GLASS
Everyday glass that is heat
resistant e.g. Pyrex
®
, is ideal.
Do not use delicate glass which
may crack due to the heat from the
food. Do not use lead crystal which
may crack or arc.
CHINA
AND CERAMIC
Everyday glazed china plates,
saucers, bowls, mugs and cups
can be used if they are heat
resistant. Porcelain and ceramic
are also ideal. Fine bone china
should only be used for reheating
for short periods, otherwise the
change in temperature may crack
the dish or craze the finish. Do not use dishes with a metal
rim or pattern. Do not use jugs or mugs with glued handles,
since the glue can melt in a microwave.
POTTER
Y, EARTHENWARE,
STONEWARE
If completely glazed, these dishes
are suitable. Do not use if partially
glazed or unglazed, since they are
able to absorb water which in turn
absorbs microwave energy, making
the container very hot and slows
down the cooking of food.
FOIL/MET
AL CONTAINERS
NEVER ATTEMPT TO COOK IN
FOIL OR METAL containers – the
microwaves cannot pass through
and the food will not heat evenly –
this may also damage your oven.
Small items in shallow foil
containers can be REHEATED in
the microwave, but take care that
containers do not touch the oven walls or door. Use wooden
kebab sticks instead of metal skewers. DO NOT RE-USE
FOIL CONTAINERS AS THEY MAY BECOME DENTED OR
DAMAGED AND ARCING MAY OCCUR.
