Microwave Cooking

What part of the microwave oven generates the microwaves? Food is cooked by vibrations that create friction which produces the heat for the food.

Parts of a Microwave  Magnetron tube and fan disperse waves- from the ceiling or side of the oven.  Door and seal should not leak- can damage eyes, etc.  Rotating tray distributes waves better than turning and rotating food manually.

How do Microwaves Work? This heat starts on the outside of the food and moves in. Microwaves penetrate food only ¾ to 1 ½ inches. Foods cook from the outside of the dish toward the center.

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

1. Microwaves are ATTRACTED to: a.Sugar b. Fat c. Water

2. Microwaves are REPELLED by: a.Metal Like What?

3. What materials or containers are microwave safe? a.Glass b.Paper c.Plastic (Heat Tempered!)

4. What part of the microwave oven generates the microwaves? The Magnetron!

5. Which container cooks more evenly… ROUNDorSQUARE Why?!? Because it allows the microwaves to enter the food from as many sides as possible. They won’t “bounce off” the corners.

6. WHAT is standing time and WHY is it important? WHAT: 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.

7. Why should you stir or rotate food 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.)

8. What part of the microwave will rotate the food WHILE it is cooking? A Turntable

Circle it! A circle is the most effective cooking shape. Foods, or the parts of foods, placed towards the center will cook more slowly. -Arrange foods so the thickest parts are toward the side of the oven.

9. 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. Why do foods NOT brown in the microwave? Because there is no dry heat to pull the moisture away from the food. VS.

11. How can you prevent burns when microwave cooking? a.Use hot pads or oven mitts b.Lift steamy lids away from you c.Use only microwave safe dishes

Use a food thermometer to be sure that meat, poultry, fish, and casseroles are thoroughly cooked.

A few safety tips... To prevent burning yourself from microwave cooking, remember: Foods can create hot containers Items can explode (egg yolk, potato). Pierce them with a fork. Lifting the cover or plastic from the food can cause a burn. Hot steam escaping can cause a burn
