472.6 USING THE MICROWAVE-ONLY FUNCTION TO RE-HEATINGHeating food in a microwave oven is much quicker and energy efficient than traditional methods.• We recommend that you heat foodstuffs (especially if they are frozen) to a temperature of at least 70° C. (itmust be piping hot!). Leave to stand for a few minutes as you will not be able to eat that food immediatelybecause it will be too hot.This will ensure that any possible bacteria present in food will have been killed.• To heat pre-cooked or frozen foods, follow these rules:- remove the food from its metal containers;- cover it with plastic wrap (the clear-film type suitable for microwave ovens) or wax paper; in this way, allthe food’s natural flavour will be preserved and the oven will stay cleaner; you may also cover the foodwith an upside-down plate;- if possible, stir or turn the food over frequently so as to speed up the heating process and keep the heatuniform at the same time;- follow the cooking times listed with great caution; remember that under certain conditions the timings givenmust be lengthened• Frozen foods must be defrosted before the heating process begins. The lower the food’s initial temperature,the longer the time needed for heating.• Foodstuffs and drinks may be heated briefly in paper or plastic containers. In any event, however, such con-tainers may become misshapen if the heating time is too long.2.5 USING THE MICROWAVE-ONLY FUNCTION TO KEEP FOOD HOTThis function enables you to keep food hot, whether that food be just cooked or re-heated, without having it getdry or stick to its container.Selecting the 1 power level and covering the food with a plate or plastic film, you will find that foods willremain warm up to serving timeYou can leave foods in their cooking container if they are covered.
