.UTENSILS GUIDELINE…。……………………… .
It is strongly recommended to use the containers which are
suitable and safe for microwave cooking. Generally speaking, the
containers which are made of heat-resistant ceramic, glass
or plastic are suitable for microwave cooking. Never use
metal containers for microwave cooking and combination
cooking as spark is likely to occur. You can take the reference of
below table.

Material
of container
Microwave Notes
Heat-resistant
ceramic
Yes
Never use the ceramics
which are decorated with
metal rim or glazed
Heat-resistant plastic Yes
Can not be used for long
time microwave cooking
Heat-resistant glass Yes
Grill rack No
Plastic film

It should not be used when
cooking meat or chops as
over-temperature may do
damage to the film
COOKING TIPS…… …
The following factors may affect the cooking result:
Food arrangement
Place thicker areas towards outside of dish, the thinner part
towards the centre and spread it evenly. Do not overlap if
possible.
Cooking time length
Start cooking with a short time setting, evaluate it after it times out
and extend it according to the actual need. Over cooking may
result in smoke and burns.
Cooking food evenly
Food such as chicken, hamburgers or steak should be turned
once during cooking.
Depending on the type of food, if applicable, stir it from outside to

21
centre of dish once or twice during cooking
Allow standing time
After cooking times out, leave the food in the oven for an
adequate length of time, this allows it to complete its cooking
cycle and cooling it down in a gradual manner
Whether the food is done
Colour and texture of food help to determine if it is done, these
include:
- Steam coming out from all parts of food, not just the edge
- Joints of poultry can be moved easily
- Pork or poultry shows no signs of blood
- Fish is opaque and can be sliced easily with a fork
Browning dish
When using a browning dish or self-heating container, always
place a heat-resistant insulator such as a porcelain plate under it
to prevent damage to the turntable and rotating ring.
Microwave safe plastic wrap
When cooking food with high fat content, do not allow the plastic
wrap come into contact with food as it may melt
Microwave safe plastic cookware
Some microwave safe plastic cookware might not be suitable for
cooking foods with high fat and sugar content. Also, the
preheating time specified in the dish instruction manual must not
be exceeded.
