CAUTION: If a container heats up more than the food you are
cooking, then it is unsuitable for microwave cooking and you
should stop using it.
Many commercially available containers
now include a microwave safe symbol
which means the manufacturer declares it
as suitable for use in a microwave oven.
Use containers with the microwave safe
symbol where possible.
General advice
Use heat resistant porcelain, glass or plastic containers made
for microwave ovens, otherwise there is a risk of shrinking,
deforming or burning. Metal containers, or containers having
metal decoration or trim are not suitable for use with your
microwave oven.
Avoid containers which narrow at the top as these may cause
the contents to erupt when removed from the oven.
Microwave containers and wraps designed for microwave ovens
are widely available. Plastic films should not touch food as they
may gas, melt or break down when hot and contaminate food.
Wax paper, oven cooking bags, parchment paper and white
microwave paper towels are safe for microwave use. Wooden
objects may catch fire, so avoid their use.
Do not use aluminium foil for microwave cooking unless the
recipe requires it. Keep foil at least 25 mm away from the oven
walls. Metal skewers, ties, etc. should be removed from food
before cooking.
