COOKING UTENSILSCOOKING INSTRUCTIONSUtensils should be checked to ensure that they are suitable for use in microwave ovens.UTENSILS TESTPlace the utensil in question next to a glass measure filled with water, in the microwave oven. Microwave athigh power for 1-2 minutes. If the water heats up, but the utensil remains cool, the utensil is microwave-safe.However if the utensil becomes warm, microwaves are being absorbed by the utensil and it should not be in themicrowave oven. You probably have many items on hand in your kitchen right now that can be used as cookingequipment in your microwave oven. Read through the following checklist.Microwave function onlyUtensils and cooking containers used in a microwaveoven should be of a material that does not act as a barrierto microwave energy. Generally this means that youshould cook in either (paper), plastic, glass or ceramic.Metal pans reflect microwave energy and inhibit cooking,and should not be used. In addition to material, the shapeof the container should also be considered. Round ovalshapes give the most even cooking. Square orrectangular containers may over-cook foods in the cornersbecause more energy is absorbed there.Shallow containers give more even cooking results.Utensils made of china and ceramic excellent to use inyour microwave oven. Most types of glass are also verygood. Lead crystal glass can crack and should therefore,not be used. Plastics and paper can also be used,provided they can withstand the temperature of theheated food. For cooking only use plastics, which willwithstand a temperature of over 120˚C, e.g. polypropeneand polyamide. Some plastic materials, e.g. melamine,will be heated by the microwave, and be damaged. Tofind out if a certain container is suitable, the followingsimple test can be made:Place the empty container and a glass of water inside themicrowave oven. The water is needed because the ovenmust not be operated empty or with empty containersonly. Let the oven work on full power for one minute. Asuitable container will only be lukewarm.Metal containers, e.g. saucepans or frying pans shouldnot be used in microwave ovens. Nor should plates orvessels with decorations be used since metal e.g. gold,might be part of the decoration and such decorations willbe damaged. Small pieces of aluminiuum foil can beused, but only to shield the areas that would over-cook(e.g. for covering chicken wings, legtips and fish tails) but the foil must nottouch the side of the oven as damagemay occur.Glass (general) No Yes (1) NoGlass (heat resistant) Yes Yes YesGlass-ceramic andceramic (heat resistant) Yes Yes (1) Yes (1)Earthenware Yes Yes YesChina (heat resistant) Yes Yes YesPlastic (general) No Yes (2) NoPlastic (heat resistant) Yes (2) Yes (2) Yes (2)Aluminium foil containers/aluminium foil Yes Yes (3) YesMetal baking tins Yes (4) No Yes (4)Metal (pots.pans, etc) Yes No NoPaper No Yes (5) No1. Without metal parts or metal trims.2. Some plastics are heat-proof only to certaintemperatures. Check carefully!3. It is possible to use aluminium foil to shield deliateareas of food (this prevents over-cooking).4. Metal tins can be used in the combination methods,however if these are very deep, they will greatlyreduce the efficiency, as metal shields themicrowave energy from the food.5. Use for short term heating and covering ; theyabsorb excess misture when warming food. Payspecial attention as over-heating may cause a fire inyour oven. Do not use re-cycled paper products, e.g.kitchen rool unless they say they are specificallydesigned for use in a microwave oven.These products contain impuities which may causesparks and/or fires when use. Caution:• There are a number of accessories available on themarket. Before you buy, make sure they are suitable formicrowave use.• When you put food in the microwave oven, make surethat food, food supports or covering do not come indirect contact with any of the internal walls or the ceilingof the cavity since discolouration may take place.Before use, the user should check that utensils are suitable for use in microwave ovens.Material GrillcookingMicrowavecookingCombinedcooking10
