A conventional oven cooks food by means of heat and it is powered by either gas or electricity. Some models of this type are designed to be gas specific or electricity powered. The downside of a conventional oven is that air is not distributed evenly on a constant basis. Circulation of heat can also be obstructed by the pans and pots placed inside the oven, causing uneven cooking. One experiment in Sweden, for example, has found out that cooking through conventional ovens used 9.5 more energy as that generated by microwaves after cooking a small but same amount of potatoes in the two kitchen devices under the same conditions. So if you're cooking big meals - a roast turkey or a big chunk of potatoes, for example - it's perfectly alright to use a traditional method of cooking, especially if the food is not fit for microwaves. The time used to microwave food is basically so short that it is hard to believe that the supposed bacteria present in foods can be killed in such a shortened time. The foods therefore cannot be considered healthy. Another point to be considered is the method of reheating leftovers. Many people use plastic wraps or aluminum foil to protect the food from microwave radiation and from spills inside the appliance. There are two basic functions that you should take note of the standard or convection. The standard microwave works best in heating food and those ready to cook meals. On the other hand, the convection microwave allows you to grill, heat, and cook since it is a combination of the features of a microwave oven and a convection oven. Use warm water to soften the tough stains or food residue. Scrub it with a sponge and trustworthy dish detergent. Make sure that it has completely dried before you place it back to the microwave oven. Have it air-dried or use a kitchen towel. Just ensure that it doesn't contain water as you put it back. Tips On Cooking Food Using Microwaves Microwave ovens have become a part of every household kitchen today. In the presence of a busy lifestyle, the microwave oven provides an effective alternative because it lessens meal preparation time by about two-thirds as compared to the traditional method of preparing and cooking food.
