UK9Like radio and television waves, microwaves areelectromagnetic waves.Microwaves are produced by a magnetron inside themicrowave oven, and these vibrate the molecules ofwater present in the food. The friction this causesproduces heat, which ensures that the food is defrosted,heated or cooked through.The secret of the reduced cooking times is the fact thatthe microwaves penetrate the food from everydirection. Energy is used to the full. In comparison, theenergy from a conventional hob passes from the burnerthrough the pan and so to the food.This method wastes a great deal of energy.THE CHARACTERISTICS OF MICROWAVESMicrowaves penetrate all non-metal objects made ofglass, china, earthenware, plastic, wood or paper. This iswhy the microwaves never make these materials hot.Dishes become hot only because the food inside them ishot.The food absorbs the microwaves and is heated.Microwaves cannot pass through objects made of metaland so they are deflected. For this reason metal objectsare not normally suitable for microwave cookery.There are exceptions where you can actually make useof the fact that the microwaves cannot pass throughmetal. If you cover food with aluminium foil at specificpoints while it is defrosting or cooking, you can preventthose parts from getting too warm, too hot, orovercooked. Please check out the advice given in theguide.Microwave operationBy using the microwave facility in your newcombination microwave oven you can, for example,quickly heat up ready-prepared meals or drinks, or meltbutter or chocolate in no time at all.The microwave oven is equally good at defrosting food.Sometimes, however, it is better to combine themicrowave with convection heating or grilling(combined operation). You can then cook the foodrapidly and brown it at the same time. Cooking timesare generally much shorter than in conventional foodpreparation.COMBINED OPERATION(MICROWAVE OPERATION WITHCONVECTION OR GRILL)By combining two modes of operation the benefits ofyour oven are cleverly linked together.You are able to choose between• microwave + convection (ideal for joints of meat,poultry, puddings, bread and cakes) and• microwave + grill (ideal for pizzas, snacks, quick fry-ups, joints, poultry, chicken legs, kebabs, Welshrarebit and cooking au gratin).Using the combination facility you can cook and brownfood at the same time.The advantage is that the convected heat or the heatfrom the grill quickly seals the pores in the outer layersof the food. The microwaves ensure a short and gentlecooking period. The juices are preserved inside the foodand the outside is crisp.Convection operationYou can also use convection without microwave. Theresult is like using a conventional oven. The circulatingair quickly heats up the external parts of the foodwithout drying up the meat juices and the foods.This sealing process means that the meals remain tastyand cook in a shorter time than with conventionalovens with upper and lower heaters.Grill OperationThis appliance comes with a quartz grill above thecooking area. It can be used as a conventional grillwithout microwave. You can quickly bake or grill dishes.It’s also suitable for steaks, chops and cakes.What are microwaves?This is what your new combinationmicrowave oven can do1.
