SUITABLE OVENWARE
1. The ideal material for a microwave utensil is transparent to microwave, it allows energy to pass through the
container and heat the food.
2. Microwave cannot penetrate metal, so metal utensils or dishes with metallic trim should not be used.
3. Do not use recycled paper products when microwave cooking, as they may contain small metal fragments which
may cause sparks and/or res.
4. Round /oval dishes rather than square/oblong ones are recommend, as food in corners tends to overcook.
5. Narrow strips of aluminum foil may be used to prevent overcooking of exposed areas. But be careful don’t use too
much and keep a distance of 2.54 cm between foil and cavity
The list below is a general guide to help you select the correct utensils.

Grill Comment
Browning dishes
/
Always follow the manufacturers instructions.
Do not exceed heating times given. Be very careful as these
dishes become very hot.
China and ceramics
/
Porcelain, pottery, glazed earthenware and bone china are
usually suitable, except for those with metallic decoration.
Heat–Resistant Glass
Care should be taken to ensure that any glass cook ware is
suitable for use in a microwave oven.
Non Heat–Resistant Glass
Heat–Resistant Ceramics
Ensure that any ceramic material is not too thick or in high in
mineral content.
Microwave–Safe Plastic Dish
Always check that the plastic cook ware is suitable to be used in
a microwave oven.
Kitchen Paper
/
Only use kitchen paper which is recommended for use in
microwave ovens.
Glassware e.g. Pyrex®
/
Care should be taken if using ne glassware as it can break or
crack if heated suddenly.
Metal Tray
It is not recommended to use metal cookware as it will arc,
which can lead to re.
Metal Rack
It is not recommended to use metal cookware as it will arc,
which can lead to re.
Aluminium foil
Foil Containers
/
Small pieces of aluminium foil can be used to shield food from
overheating. Keep foil at least 2.54 cm from the oven walls, as
arcing may occur.
Foil containers are not recommended unless speci ed by the
manufacturer, e.g. Microfoil®, follow instructions carefully.
Cling lm
It should not touch the food and must be pierced to let the
steam escape.
Plastic/Polystyrene e.g fast food
containers
Care must be taken as some containers warp, melt or discolour
at high temperatures.
Freezer/Roasting bags
Must be pierced to let steam escape. Ensure bags are suitable
for microwave use.
Paper - Plates, cups and kitchen
paper
Do not use plastic or metal ties, as they may melt or catch re
due to the metal ‘arcing’.
Straw and wooden Containers
Only use for warming or to absorb moisture.
Care must be taken as overheating may cause re.
Recycled paper and newspaper
Always attend the oven when using these materials as
overheating may cause re.
May contain extracts of metal which will cause ‘arcing’ and may
lead to re.
WARNING: When heating food in plastic or paper containers, monitor the oven due to the possibility of
ignition.
NOTE: Do not leave your oven unattended while in use.

MICROWAVE COOKING ADVICE
Microwaves cook food faster than conventional cooking. It is therefore essential that certain techniques are followed
to ensure good results. Many of the following techniques are similar to those used in conventional cooking.
WARNING: Liquids and foods must not be heated in sealed containers or jars/containers with lids on, as
pressure will build up inside and may cause the jar/container to explode.
COOKING ADVICE NOTES:
• Always attend the oven when in use.
• Ensure that the utensils are suitable for use in a microwave oven.
• Only use microwave popcorn within the recommended packaging (follow the manufacturers instructions). Never
use oil unless speci ed by the manufacturer and never cook for longer than instructed.
WARNING: If you exceed recommended cooking times and use power levels that are too high, food
may overheat, burn and, in extreme circumstances, catch re and damage the oven.
Arrange
Place the thickest parts of food towards the outside of the dish. e.g. Chicken drumsticks.
Foods that are placed towards the outside of the dish will receive more energy, so cook quicker, than those in the
centre.
Cover
Certain foods bene t from being covered during microwave cooking.
Use vented microwave cling lm or a suitable lid.
Pierce
Foods with a shell, skin or membrane must be pierced in several places before cooking or reheating as steam will build
up and may cause food to explode. e.g. Potatoes, Fish, Chicken, Sausages.
NOTE: Eggs should not be heated using microwave power as they may explode, even after cooking has ended. e.g.
poached, fried, hard boiled.
Stir, turn and rearrange
For even cooking it is essential to stir, turn and rearrange food during cooking. Always stir and rearrange from the
outside towards the centre.
Stand
Standing time is necessary after cooking so it enables the heat to disperse equally throughout the food.
