Microwave Cooking

How it Works

Electromagnetic wave emitted by a magnetron tube and set in motion by a fan or turn table

Some areas get more microwaves, resulting in uneven cooking—rotating helps cook evenly

Microwaves are attracted to water, fat, and sugar molecules causing them to vibrate and heat

Waves are emitted from an opening in the metal case.

Waves are then reflected off the sides and penetrate food in the process.

Safety Features

Seal around door

Door Safety Switch/Short Circuit Safety Switch (turns off when you open the door)

Do not attempt to use if the door does not seal properly, is bent, or hinges or latches are broken!

Utensils

Best to use glassware, china, or ceramic dishes

Plastic and paper are good for reheating, but not for prolonged cooking. They cannot withstand high temperatures.

Make sure steam can escape or have room to build up

Avoid wax coated materials, delicate glass and anything containing metal

Is it safe to use?

Put an empty container in the microwave for 1 minute. Safe cookware should still be cool.

orMeasure 1 cup of water and put it in the dish

in question. Cook for 1 ½ -2 min. If the dish stays cool, it is safe to use in the mirowave.

Shapes and Arrangements

Foods cook around the outside edges first. Position heavier/denser portions on the outside.

Centers should be left empty, except when cooking 1 item.

Use a glass or bowl to keep the center open

Position Items 1” Apart

Shapes Etc. (cont.)

Rotate dish(es) ¼ turn once or twice during cooking

Round shapes cook more evenly—corners have more energy passed through them and may overcook

High/tall foods close to the top also receive more energy

Cooking / Reheating• Defrost and various power levels indicate

the auto shutoffs at certain intervals

• Stir while cooking to prevent uneven cooking

• Cooking times will differ for every appliance as well as volume of food, size, and cooking utensil

Cooking Tips

Covering while microwaving evokes similar results from conventional cooking-steam is retained to tenderize food and shorten cooking time.

Shield some portions that are particularly sensitive to overcooking.

Standing Time

Recipes allow for “standing time.”This is the amount of time that it takes

for the food molecules to stop vibrating after the microwave process ends.

Cooking continues during this period of time, so it is factored into the recipe’s time requirement.

Guidelines for Using Foil

Food quantity is much greater than foil/skewers

Metal/foil is grounded along the bottom of microwave

Browning

Foods cooked in a microwave often do not have time to brown/crisp.

Additional ingredients can be used to create a browning effect:

Browning Alternatives

Teriyaki/soy sauce BBQ Sauce Melted Butter Worcestershire/steak sauce Bread crumbs Shredded Cheese Brown Sugar Nuts Jellies, Preserves, and Glazes

Benefits

Time Savings-cook 3-4 times faster than ovens

Energy Savings—Used up to 14% electricity of conventional oven and less power for a shorter period of time

No preheatingAuto-turn offQuick and easy cleanup
