Choosing the correct container is a very
important factor in deciding the success or
failure of your cooking.
Testing Dishes for Suitability
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 (½pt) 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.
Note
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.
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.
