Food CharacteristicsCooking Techniques
Bone and Fat
Both bone and fat affect cooking. Bones may
cause irregular cooking. Meat next to the tips of
bones may overcook while meat positioned
under a large bone, such as a ham bone, may
be undercooked. Large amounts of fat absorb microwave ener-
gy and the meat next to these areas may overcook.
Density
Porous, airy foods such as breads, cakes or
rolls take less time to cook than heavy, dense
foods such as potatoes and roasts. When
reheating donuts or other foods with different
centers be very careful. Certain foods have
centers made with sugar, water, or fat and
these centers attract microwaves (For example, jelly donuts).
When a jelly donut is heated, the jelly can become extremely
hot while the exterior remains warm to the touch. This could
result in a burn if the food is not allowed to cool properly in the
center.
Quantity
Two potatoes take longer to cook than one potato. As
the quantity of the food decreases so does the cook-
ing time. Overcooking will cause the moisture content
in the food to decrease and a fire could result. Never
leave microwave unattended while in use.
Shape
Uniform sizes heat more evenly. The thin
end of a drumstick will cook more quickly
than the meaty end. To compensate for
irregular shapes, place thin parts toward the
center of the dish and thick pieces toward
the edge.
Size
Thin pieces cook more quickly than thick
pieces.
Starting Temperature
Foods that are at room temperature take less time to
cook than if they are chilled, refrigerated, or frozen.
Piercing
Foods with skins or membranes must be
pierced scored or have a strip of skin
peeled before cooking to allow steam to
escape. Pierce clams, oysters, chicken liv-
ers, whole potatoes and whole vegetables.
Whole apples or new potatoes should have
a 1-inch strip of skin peeled before cooking. Score sausages
and frankfurters. Do not Cook/Reheat whole eggs with or with-
out the shell. Steam build up in whole eggs may cause them to
explode, and possibly damage the oven or cause injury.
Reheating SLICED hard-boiled eggs and cooking
SCRAMBLED eggs is safe.
Browning
Foods will not have the same brown appearance
as conventionally cooked foods or those foods
which are cooked utilizing a browning feature.
Meats and poultry may be coated with browning
sauce, Worcestershire sauce, barbecue sauce
or shake-on browning sauce. To use, combine
browning sauce with melted butter or margarine and brush on
before cooking. 
For quick breads or muffins, brown sugar can be used in the
recipe in place of granulated sugar, or the surface can be
sprinkled with dark spices before baking.
Spacing
Individual foods, such as baked potatoes, cup-
cakes and appetizers, will cook more evenly if
placed in the oven equal distances apart.
When possible, arrange foods in a circular pat-
tern.          
						

							21
Cooking Techniques(continued)
Covering
As with conventional cooking, moisture evaporates during
microwave cooking. Casserole lids or plastic wrap are used for
a tighter seal. When using plastic wrap, vent the plastic wrap
by folding back part of the plastic wrap from the edge of the
dish to allow steam to escape. Loosen or remove plastic wrap
as recipe directs for stand time. When removing plastic wrap
covers, as well as any glass lids, be careful to remove them
away from you to avoid steam burns. Various degrees of mois-
ture retention are also obtained by using wax paper or paper
towels. 
Shielding
Thin areas of meat and poultry cook more quickly than meaty
portions. To prevent overcooking, these thin areas can be
shielded with strips of aluminum foil. Wooden toothpicks may
be used to hold the foil in place.
CAUTION is to be exercised when using foil. Arcing can
occur if foil is too close to oven wall or door and damage to
your oven will result.
Cooking time
Arange of cooking time is given in each recipe. The time
range compensates for the uncontrollable differences in food
shapes, starting temperature, and regional preferences.
Always cook food for the minimum cooking time given in a
recipe and check for doneness. If the food is undercooked,
continue cooking. It is easier to add time to an undercooked
product. Once the food is overcooked, nothing can be done.
Stirring
Stirring is usually necessary during microwave cooking. Always
bring the cooked outside edges toward the center and the less
cooked center portions toward the outside of the dish.
Rearranging
Rearrange small items such as chicken pieces, shrimp, ham-
burger patties, or pork chops. Rearrange pieces from the edge
to the center and pieces from the center to the edge of the
dish.
Turning
It is not possible to stir some foods to distribute the heat even-
ly. At times, microwave energy will concentrate in one area of
the food. To help insure even cooking, these food need to be
turned. Turn over large foods, such as roasts or turkeys,
halfway through cooking.
Stand Time
Most foods will continue to cook by conduction after the
microwave oven has turned off. In meat cookery, the internal
temperature will rise 5°F to 15°F (3°C to 8°C), if allowed to
stand, tented with foil, for 10 to 15 minutes. Casseroles and
vegetables need a shorter amount of standing time, but this
standing time is necessary to allow foods to complete cooking
to the center without overcooking on the edges.
Test for Doneness
The same tests for doneness used in conventional cooking
may be used for microwave cooking. Meat is done when fork-
tender or splits at fibers. Chicken is done when juices are clear
yellow and drumstick moves freely. Fish is done when it flakes
and is opaque. Cake is done when a toothpick or cake tester is
inserted and comes out clean.
ABOUT FOOD SAFETY AND COOKING
TEMPERATURE
Check foods to see that they are cooked to the United States
Department of Agriculture’s recommended temperatures.
TEMP FOOD
160˚F ...for fresh pork, ground meat, boneless white 
poultry, fish, seafood, egg dishes and frozen
prepared food.
165˚F ...for leftover, ready-to-reheat refrigerated, and
deli and carryout “fresh” food.
170˚F ...white meat of poultry.
180˚F ...dark meat of poultry.
To test for doneness, insert a meat thermometer in a thick or
dense area away from fat or bone. NEVER leave the ther-
mometer in the food during cooking, unless it is approved for
microwave oven use.

Care and Cleaning of Your Microwave Oven
BEFORE CLEANING:
Unplug oven at wall outlet. AFTER CLEANING:
Be sure to place the Roller Ring and the Glass Tray in the
proper position and press Stop/Reset Pad to clear the
Display.
Inside of the oven:
Wipe with a damp cloth after using.
Mild detergent may be used if need-
ed. Do not use harsh detergents or
abrasives.Glass Tray:
Remove and wash in warm soapy
water or in a dishwasher.Outside oven surfaces:
Clean with a damp cloth. 
To prevent damage to the operating parts
inside the oven, water should not be
allowed to seep into ventilation openings.
Oven Door:
Wipe with a soft dry cloth when steam accumulates inside
or around the outside of the oven door. During cooking,
especially under high humidity conditions, steam is given
off from the food. (Some steam will condense on cooler
surfaces, such as the oven door. This is normal.)
Inside surface is covered with a heat and vapor barrier
film. Do not remove.
Roller Ring and oven cavity floor:
Clean the bottom surface of the oven with mild detergent
water or window cleaner, and dry. Roller Ring may be
washed in mild soapy water or dishwasher. These areas
should be kept clean to avoid excessive noise.Control Panel:
* Covered with a removable protective film
to prevent scratches during shipping.
Small bubbles may appear under this film.
(Hint - To remove film, apply masking or
clear tape to an exposed corner and pull
gently.)
* If the Control Panel becomes wet, clean it
with a soft dry cloth. Do not use harsh
detergents or abrasives.
IT IS IMPORTANT TO KEEP THE OVEN CLEAN AND DRY. FOOD RESIDUE AND CONDEN-
SATION MAY CAUSE RUSTING OR ARCING AND DAMAGE TO THE OVEN. AFTER USE,
WIPE DRY ALL SURFACES-INCLUDING VENT OPENINGS, OVEN SEAMS, AND UNDER
GLASS TRAY.
