The boiling wand ensures that the liquid heats up evenly with
bubbles forming at the right time.
When reheating liquids, always place the boiling wand supplied into
the cup or glass. When boiling and in particular when reheating
liquids, milk, sauces etc, using microwave power without the boiling
wand, 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 "superheating" 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. The user could be injured
and the appliance damaged.
Ensure you use only the boiling wand supplied with your appliance.
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.
