When unsure that a cooking
con tainer is suitable for use in
your microwave, check by the
follow ing test:
1. Fill a microwave safe
measur ing jug with 300ml
(
1
⁄
2
pt) cold water.
2. Place it on the turntable
along side the dish to be
tested. If the dish you are
testing is a large dish, then
stand the measur ing jug on
top of the empty dish.
3. Heat on HIGH power for
1 minute.
Result
If the dish is suitable for
micro waving, 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 obvious ly
absorbing microwave energy.
N.B. This test does not apply
to plastic or metal based
con tainers e.g. Le Creuset
®
style dishes, which should not
be used as they are cast iron
covered with enamel.
Containers to use
Oven glass
Everyday glass that is
heat resistant e.g.
Pyrex
®
, is ideal for
Microwave cooking.
Do not use delicate
glass or lead crystal
which may crack or
arc.
China and ceramic
Everyday glazed
china, porcelain or
ceramic plates, bowls,
mugs and cups can
be used if they are
heat resis tant. Fine
bone china should
only be used for
reheating for short
periods. Do not use
dishes with a metal rim or pattern. Do not use
jugs or mugs with glued handles, since the
glue can melt.
Pottery, 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/metal containers
NEVER ATTEMPT TO
COOK IN FOIL OR
METAL con tai ners on
Microwave only as the
microwaves cannot
pass through and the
food will not heat
evenly, it may also
damage your oven.
Quick check guide to cooking utensils
Choosing the correct container is a very important factor in deciding the success or
failure of your cooking.
