126. Liquids.Liquids and other foods must not be heated in sealed containers since they are liable toexplode. When heating liquids, eg soup, sauces and beverages in your microwave oven,overheating the liquid beyond boiling point can occur without evidence of bubbling.This could result in a sudden boil over of the hot liquid. To prevent this possibility the followingsteps should be taken:a) Avoid using straight-sided containers with narrow necks.b) Do not overheat.c) Stir the liquid before placing the container in the oven andagain halfway through the heating time.d) After heating, allow to stand in the oven for a short time, stirring again before carefullyremoving the container.e) Microwave heating of beverages can result in delayed eruptive boiling, therefore careshould be taken when handling the container.7. Lids.Always remove the lids of jars and containers and takeaway food containers before youmicrowave them. If you don’t then steam and pressure might build up inside and cause anexplosion even after the microwave cooking has stopped.8. Deep Fat Frying.Do not attempt to deep fat fry in your oven.9. Meat Thermometer.Use a meat thermometer to check the degree of cooking of roastsand poultry only when meat has been removed from the microwave.If undercooked, return to the oven and cook for a few more minutesat the recommended power level. Do not leave a conventional meatthermometer in the oven when microwaving.10. Paper, Plastic.When heating food in plastic or paper containers, keep an eye onthe oven due to the possibility of ignition. Do not use wire twist-tieswith roasting bags as arcing will occur.Do not use re-cycled paper products, e.g. Kitchen roll unless they saythey are specifically designed for use in a microwave oven. Theseproducts contain impurities which may cause sparks and/or fires whenused.11. Reheating.It is essential that reheated food is served “piping hot”.Remove the food from the oven and check that it is “piping hot”, i.e.steam is being emitted from all parts and any sauce is bubbling. (Ifyou wish you may choose to check the food has reached 72˚C with afood thermometer – but remember do not use this thermometerinside the microwave.)For foods that cannot be stirred, e.g. lasagne, shepherds pie, thecentre should be cut with a knife to test it is well heated through.Even if a manufacturer’s packet instructions have been followed always check the food ispiping hot before serving and if in doubt return your food to the oven for further heating.
