Microwave defrosting, reheating and cooking
When heating liquids, milk, sauces
etc, using microwave power, 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, which can lead
to the liquid boiling over suddenly
and explosively. The formation of
bubbles can be so strong that the
pressure forces the oven door open.
To avoid this, stir liquid before
heating it up. After heating it up wait
for at least 20 seconds before
removing the container from the
oven. Placing a suitable glass rod or
similar utensil in the container can
help prevent it from boiling over.

Tips on cooking
Food with a thick skin or peel, such
as tomatoes, sausage, potatoes and
aubergines can burst when heated.
Pierce or score the skin of these
types of food several times to allow
steam to escape.
Eggs heated in their shells can burst,
even after they have been taken out
of the oven.
Eggs can only be cooked in their
shells in the microwave oven in a
specially designed egg-boiling
device available from specialist
shops.
If you cook eggs without their shells
using microwave power, the yolks
could explode due to the resulting
pressure.
Prick the yolk several times before
cooking to avoid this.
