When using microwave power you
should always place the food / dish
centrally on the glass tray and slide
the tray into the first shelf level from
the bottom. Placing the dish on the
floor of the oven will give
unsatisfactory and uneven results.
The material and shape of containers
used affect cooking results and times.
Heat distribution is more even in round
and oval shaped flat containers than in
rectangular containers, providing better
results.
Metal containers, aluminium foil and
metal cutlery, or china with metallic
decoration such as gold rims or
cobalt blue must not be used in
microwave mode.
The metal reflects the microwaves,
hindering the cooking process.
