
Pressure can build up when reheating food or drinks in sealed
containers, jars or bottles, which can cause them to explode. Never
cook or reheat food or liquids in sealed containers, jars or bottles.
Open containers beforehand. In the case of baby bottles, the screw
top and teat must be removed.

When heating food, and in particular liquids, the boiling point may
be reached without the production of typical bubbles. Liquids do 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.
Stir liquids well before heating. After heating, wait at least
20 seconds before removing the container from the oven. In
addition, a glass rod or similar item, if available, can be placed in the
container during heating.

If you cook eggs without their shells, the yolks could explode due
to the resulting pressure.
Prick the yolk several times before cooking to avoid this.

Eggs heated in their shells can burst, even after they have been
taken out of the oven compartment.
Eggs can only be cooked in their shells in a specially designed egg-
boiling device. Do not reheat hard boiled eggs using M Chef
functions.

Food with a thick skin or peel, such as tomatoes, sausages,
potatoes and eggplants can burst when heated.
Pierce or score the skin of these types of food several times to allow
steam to escape.

Do not use a thermometer containing mercury or liquid as these
are not suitable for use with very high temperatures and break very
easily.
Only use the Miele food probe supplied with the appliance to
measure the temperature of the food.
