IMPORTANT SAFETY INSTRUCTIONS
15
When boiling and in particular when re-heating liquids, milk,
sauces etc., using microwave power without a boiling rod, the
boiling point of the liquid may be reached without the production of
typical bubbles. The liquid does not boil evenly throughout. This so-
called 'boiling delay' can cause a sudden build up of bubbles when
the container is removed from the oven or shaken. This can lead to
the liquid boiling over suddenly and explosively. Danger of scalding
and burning! The formation of bubbles can be so strong that the
pressure forces the oven door open, with a danger of injury and
damage.
Before cooking or reheating, thoroughly stir the liquid. Then wait at
least 20 seconds before removing the container from the oven.
During cooking and reheating you can also place a glass rod or
similar in the container and use as a boiling rod, if available.
Eggs can be cooked without their shells using microwave power
only if the yolk membrane has been punctured several times first.
The pressure could otherwise cause the egg yolk to explode.
Eggs in their shells will explode if cooked with microwave power,
even after taking them out of the oven.
They can only be cooked in their shells using microwave heat in a
specially designed egg-boiling device available from specialist
shops. Hard-boiled eggs must not be reheated in the microwave
oven either as they too will explode.
Food with a thick skin or peel, such as tomatoes, sausage,
potatoes and eggplant, should be pierced or cut in several places to
allow steam to escape and prevent the food from bursting.
To check food temperature, first interrupt the cooking process.
Only use a thermometer specifically approved for food use to
measure the temperature of the food. Do not use a thermometers
containing mercury or liquid as these are not suitable for use with
very high temperatures and break very easily
