Microwaves penetrate the surface of the food to a
depth of about two to three centimetres and then the
heat is gradually conducted in a random pattern.
Some parts of food matter cook faster than others.
Special microwave techniques are used to promote 

Size and Quantity
Small portions cook faster than large portions. As 
you increase the quantity of food you put into the
microwave oven, you must also increase your 
cooking time. The microwave oven has the same
power regardless of quantity; thus the power is divided
between more items and so it takes longer to cook.
As a general guide, if you double the quantity of
food suggested in the recipe, add half the time
suggested again.

Liquid Content
Low moisture foods take a shorter time to cook than
foods with a lot of moisture.

Shape
Uniform sizes cook more evenly. To compensate for
irregular shapes, place thin pieces towards the
centre of the dish and thicker pieces towards the
outer edge of the dish.

Bone and Fat
Bones conduct heat and cause the meat next to
them to be heated more quickly. Large amounts of
fat absorb microwave energy and the meat next to
these areas may overcook.

Starting Temperature
Food which has been sitting at room temperature takes
less time to cook than refrigerated or frozen food.

Density and Composition
Porous, airy foods (cakes and breads) take less time
to cook than heavy compacted foods (meat and
vegetables). Recipes high in fat and sugar content
cook more quickly.

Recipes displaying these symbols may be cooked
using these features.

fast and even cooking. Some of these techniques are
similar to those used in conventional cooking, but
because microwaves produce heat very quickly they
are extremely important. It’s a must for you to be
familiar with the following tips.

Timing
A range of cooking times is given in each recipe for
two reasons. First, to allow for the uncontrollable
differences in food shapes, starting temperatures and
personal preferences. Secondly, these allow for the
differences in electrical voltage input which changes
during peak load periods. Always remember that it is
easier to add time to undercooked food. Once the
food is overcooked, nothing can be done. For each
recipe, an approximate cooking time is given.

Stirring
Stirring is often necessary during microwave
cooking. We have noted when stirring is helpful in
the recipes. Always bring the outside edges towards
the centre and the centre portions to the outside.

Rearranging or Turning
Some foods should be turned in the container during
cooking. For example, because of the different
thicknesses in the breast and back sections of
poultry, it is a good idea to turn poultry over once to
ensure more even cooking. 
Rearranging or turning over uneven shaped food in
the dish should be done as suggested to ensure a
satisfactory result. Rearrange small items such as
chicken pieces, prawns, hamburger patties, nuts or
potatoes. Rearrange pieces from the centre to the
edge of the dish.

Cooking in Layers
Cooking in layers is not always successful as it takes
twice as long to cook a single layer and cooking may
be uneven. You can successfully reheat two dinner
plates of food at one time but remember to increase
the reheating time and use a microwave warming rack.

Piercing of Foods
Pierce the skin or membrane of foods such as
eggs, tomatoes and jacket potatoes. when cooked
whole in the microwave oven. This allows steam to
escape. If the skin has not been pierced, food may
burst.

Cured Meats
Cured meats may overcook in some areas due to
the high concentration of salts used in the curing
process. So take care when cooking different brands
of bacon as cooking times may vary slightly.
