1. What part of the microwave oven
generates the microwaves?
The Magnetron!
Food is cooked by
vibrations that
create friction
which produces
the heat for the
food.
2. Why do foods NOT brown in the
microwave?
Because there is no dry heat to pull the
moisture away from the food.
VS.
3. Foods with high water content cook
more quickly. This is good for foods like
vegetables, but bad for thick skinned
food like
– Eggs
– Squash
– Potatoes
– Hot dogs
4. Microwaves are ATTRACTED to:
a.Sugar
b. Fat
c. Water
BEWARE: These may cause Hot Spots!
5. What materials or containers are
microwave safe?
a.Glass
b.Paper
c. Plastic
(Heat Tempered!)
6.
7. Microwaves are REPELLED by:
a.Metal
Like What?
It will cause arcing electrical sparks that
can damage the oven or start a fire.
8. Which container cooks more evenly…
ROUND
or
SQUARE
Why?!?
Because it allows the microwaves to enter
the food from as many sides as possible.
They won’t “bounce off” the corners.
9. Circle it!
• A circle is the most effective
cooking shape. Foods, or the
parts of foods, placed towards
the center will
cook more slowly.
Why is it best to cover most foods when
microwave cooking?
a. It holds in steam to shorten cooking
time
b. Keeps food moist
c. Keeps foods from splattering
10. Use these materials to
cover the food:
• 1. PAPER: absorbs moisture and
prevents foods from getting soggy.
• 2. WAX: retains heat and allows
moisture to escape.
• 3. PLASTIC: holds in moisture for
foods that might dry out.
11. How can you prevent burns when
microwave cooking?
a. Use hot pads or oven mitts
b. Lift steamy lids away from you to
shield you from the steam.
c. Use only microwave safe dishes
12. What part of the microwave will
rotate the food WHILE it is cooking
to distribute the heat evenly?
The Turntable
But even then….
Stir or rotate foods ½ way through
when microwave cooking
It helps the food cook more evenly
by redistributing the heat.
(Foods cooked in the microwave will
cook from the edges in.)
13. WHAT is Microwave time?
The actual time that food cooks with
microwave energy.
WHAT is standing time and WHY is it
important?
The amount of time food is allowed
to sit AFTER microwave cooking in
order to finish the cooking
process.
WHY: If you don’t allow for standing
time, you will overcook your food.
14. Use a food thermometer to be
sure that meat, poultry, fish, and
casseroles are thoroughly cooked.
