Microwaves
– are reflected by metal,
–
pass through glass and chinaware,
–
and are absorbed by food.
Material and shape
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
Metal containers, aluminium foil and
metal cutlery, or china with metallic
decoration, such as gold rims or co
-
balt blue must not be used in an
oven being used in microwave
mode.
The metal reflects the microwaves, hin-
dering the cooking process.
Exceptions:
– If recommended by the producer,
pre-cooked meals packed in alu-
minium foil containers can be de-
frosted and reheated in the micro
-
wave oven. Important: remove the lid
first.
However, as food is only heated from
the top it is better to remove the food
from the aluminium foil container and
transfer it to a dish suitable for a mi
-
crowave oven. The heat distribution
will be more even.
If sparks and arcing occur when us
-
ing a metal container, stop and trans
-
fer the food to a microwave safe con
-
tainer.
