A magnetron in a microwave oven generates electromagnetic waves of very high frequency and very short wavelength, hence the name microwave.
When food and similar substances are subjected to microwaves, they absorb energy and heat very quickly.
The actual heating takes place by molecular friction within the food itself. This is why the surrounding area does not get hot. Because...
Boiling is a method of cooking by complete immersion of food in water or stock at 100C. It is most commonly used to cook vegetables.
Principles
1. Root vegetables must be started in cold water so as to leach out acrid flavours and certain chemicals that the raw vegetables contain. They may be covered with a lid during cooking. Salt should be added when the vegetables reach the boil.

You have probably heard that pork is \"the other white meat\", but you might not have discovered many ways of cooking this delicious meat. Pork is a great alternative to chicken as a way of getting nutrients that your body needs, and you should try to eat pork at least a couple of times a week.
However I know that sometimes it can be boring eating the same meals every night, so here you...
Shallow-frying includes sauting, sweating and stir-frying. A frying pan is usually chosen for shallow-frying, but for large quantities some kitchens use a shallow tilting pan or brat pan. Good shallow-frying requires complete attention and skilled heat control. Because a small amount of frying medium is used in relation to the quantity of food being fried, the food may be easily burnt or...
From time to time, the professional cook is called upon to prepare a spit roast in the open air and some knowledge of this procedure is therefore necessary. The equipment may be hired or permanently installed. Hired equipment may be fired with bottled gas in a similar way to a barbeque grill, or it may require solid fuel such as wood and heat beads. Spits should be electrically operated from...
True roasting involves cooking meat (including poultry and game) on a roasting spit near a hot fire. Although spit roasting is popular, general-purpose or forced-air convection ovens are commonly used for roasting. Electric rotisseries are sometimes used for roasting chickens in large quantities.
Principles
1. Only prime-quality cuts of meat and poultry should be selected for roasting.

Grilling and deep-frying are the most widely used methods of cookery at the present time. The heat source of the griller may be above or below the food. Sometimes it is from both directions at once, as in the case of infra-red grillers or double-sided grills.
Large grill-plates have two or three separate heat controls, which should be adjusted to produce one very hot zone to sear all...
Deep-frying involves the immersion of food in hot oil or fat to cook it to a crisp golden colour. Meat, fish and poultry are usually coated with crumbs or batter. The popularity of deep-fried food makes it a part of every catering operation. Since the development of good frying compounds and improved deep-fryer design, the responsibility rests with the cook to produce first-class deep-fried...
Cooking involves the application of heat to foodstuffs. The basic object of cooking is to tenderize (or in the case of flour goods such as cake, to stabilize) food so that it will be easier to digest. There are two other reasons for cooking food. One is related to taste and the physical aspects of eating and nourishment of the body; the other concerns social values related to the preparation...
I'd like to talk to you about your voice. This could be a bit difficult considering I've probably never heard your voice before. Actually, I don't believe anyone has really heard your voice! Do you know why? Because you're too afraid to let anyone hear your real voice. I'm talking about your advertising voice of course, and no-one has heard it because it's much easier to run with the crowd...
