THE PRINCIPLES OF MICROWAVE COOKING
Microwaves are a form of high frequency radio waves similar to those used by a radio including AM, FM and CB.
Electricity is converted into microwave energy by the magnetron tube. From the magnetron tube, microwave
energy is transmitted to the oven where it is reflected, transmitted and absorbed by the food.
Reflection
Microwaves are reflected by metal just as a ball is bounced off of a wall. For this reason, metal utensils are not
suitable for use in the microwave. A combination of stationary interior walls and a rotating metal turntable or stirrer fan
helps assure that the microwaves are well distributed within the oven cavity to produce even cooking.
Transmission
Microwaves pass through some materials such as paper, glass and plastic much like sunlight shining through a
window. Because these substances do not absorb or reflect the microwave energy, they are ideal materials for
microwave oven cooking containers.
Absorption
During cooking, microwaves will be absorbed by food. They penetrate to a depth of about 3/4 to 1 1/2 inches.
Microwave energy activates the molecules in the food (especially water, fat and sugar), and heat is produced. If you
vigorously rub your hands together, you will feel heat produced by friction. The internal cooking of larger foods is done
by conduction as the heat which is produced by friction is conducted to the middle of the food. Foods also continue to
cook by conduction during standing time.
FOOD CHARACTERISTICS
Quantity: The amount of food placed in a microwave oven has a direct effect on the cooking time. Small amounts of food
or liquid require less cooking time than larger amounts of the same substance. As quantity increases, concentration
decreases.
Size: Small pieces cook faster than large ones. To speed cooking, cut pieces smaller than two inches (5 cm), so microwaves
can penetrate to the middle from all sides. Pieces which are similar in size and shape cook more evenly.
Shape: Many foods are uneven, like a chicken, ribs or broccoli. The thin parts will cook faster than the thick parts, while
uniformly thick foods cook evenly. To compensate for irregular shapes, place thin pieces toward the center of the dish
and thicker pieces toward the edge of the dish.
Starting Temperature: Frozen or refrigerated foods take longer to cook than foods at room temperature.
Bone and Fat: Because bones conduct heat, the side of the meat the bone is on will cook first, while boneless cuts cook
slower but more evenly. Fat attracts microwaves. The middle of these foods are cooked by heat conduction.
Moisture Content: Microwaves are attracted by moisture. Naturally moist foods absorb microwaves better than dry ones.
Add a minimum of liquid to moist foods, as excess water slows cooking.
Density: The density of food determines how easily the microwaves can penetrate and how quickly it will cook. Porous
foods, like chopped beef or mashed potatoes, microwave faster than dense ones like steak or whole potatoes.
Piercing: Steam builds up pressure in foods which are tightly covered by a skin or membrane. Pierce potatoes, egg yolks
and chicken livers to prevent bursting.
MICROWAVE TECHNIQUES
Stirring: Stir foods from outside to center of dish once or twice during cooking to equalize heat and speed microwaving.
Foods will not burn or stick, so there’s no need to stir constantly as you do in conventional cooking.
Arrangement: Arrange foods with thin or delicate ends, Iike drumsticks or asparagus spears, with the thick or tougher
portions to the outside of the dish. The parts which need more cooking will receive more energy, so food will microwave
evenly.
Spacing: Individual foods, such as baked potatoes and cupcakes will cook more evenly if placed in the oven an equal
distance apart. When possible, arrange foods in a circular pattern. Similarly, when placing foods in a baking dish, arrange
around the outside of the dish, not lined up next to each other. Food should not be stacked on top of each other.
Rearrangement: Rearrange overlapping areas, Iike tails of long fish fillets, from top to bottom, and closely packed pieces, like
meatballs, from the outside to the center of the dish.
Standing Time: Standing time is especially important in microwave cooking. Microwave energy creates heat in the outer
layers of the food. As a result of normal conduction, the food continues to cook for a few minutes after removal from the oven.
Letting roasts, large whole vegetables, casseroles and cakes stand to finish cooking allows the middles to cook completely
without overcooking, drying or toughening the outsides.
