Microwave Cooking

Dos and Don’ts of Microwave Cooking

• Always use microwave-safe containers for heating and cooking. Cookware that is specifically labeled as “microwave safe” can be used in the microwave. Some manufacturers may even print microwave safety cooking tips, or look for a microwave symbol of four parallel waves, a sign that the cookware is intended for use in microwave ovens.
• Plastic containers should be avoided, unless labeled “microwave safe”. Harmful compounds from the plastic may leak into the food and pose a health hazard. Do not use newspapers and brown paper bags, they can catch fire. Even the use of aluminum foil is not recommended for use in microwaves, unless explicitly stated. Never use ice cream and margarine tubs or one-time use plastic bowls. Glass containers can be used only if they are labeled “microwave safe”.
• Metal containers are a strict no-no. The microwaves are unable to pass through metal, and the food will never get heated. Moreover, there is a danger of the metal converting the microwaves into electric current, that may even cause a spark. This also holds true for metal wires, especially the ones used in Chinese take-away cartons. Transfer the food to a microwaveable bowl if you want to heat it.
• Microwaves may cook food unevenly if it is composed of large chunks. If possible, cut the food into smaller pieces for even cooking. Arrange the food evenly in the container and not bunched up to one side to ensure it gets cooked properly.
• It is recommended that you cover the container with a lid; this ensures uniform cooking. Do not close the lid tightly, leave a small gap to allow the steam to escape. You can use Saran Wrap to cover the food, just spike it in a couple of places to let steam escape. Stir the food, or rotate it, if it’s too chunky, at least once during the cooking cycle.
• 
• Preferably, use shallow containers to cook food. Food stored in them will get cooked uniformly as compared to foods in high-walled containers.
• When heating packaged frozen foods, follow the instructions on how to reheat very carefully. Pierce the thin plastic wrap so the steam escapes, and once done, carefully lift the wrap with the opening facing away from you. Do not let the plastic come in direct contact with the food.
• If you are heating foods high in fats, it’s better to stick to glass containers. There is a risk of chemical additives from plastic dissolving and contaminating fatty foods at very high temperatures.
• Never run a microwave if it is empty. With nothing to absorb the radiation that is being produced, the energy can actually burn out the tube inside, posing a fire hazard.
• Microwaves should not be used to sterilize bottles. Use your gas stove to boil water and sterilize baby bottles and jars, even though it takes a longer time.
• Never let children use a microwave without adult supervision. Make sure they do not stand too close to the microwave when it’s on. Use the child safety lock if your microwave is equipped with one.
• It’s equally important to clean your microwave on a regular basis which gets rid of any stuck and burnt food particles. Do not attempt to repair the microwave on your own. If you notice any corrosive damage or unhinged door, stop using it and take it to a repair shop.
