Certain Plastics
While some plastics are safe, others can melt or leach harmful chemicals when heated. Avoid containers that are not explicitly labeled as microwave-safe. Containers marked with recycling codes 3, 6, and 7 may contain BPA or other harmful chemicals that can seep into food when heated.
Eggs in Their Shells
Microwaving whole eggs can lead to a messy explosion as the steam builds up and has no way to escape. Instead, beat the eggs and then microwave them in a suitable container.
Pepper and Spices
Microwaving spices can sometimes cause them to release too much heat and lead to a loss of flavor. Instead of microwaving spices, consider adding them to your dish after it has been heated.
The Right Storage for Microwaving
Proper storage of food in the microwave is crucial for safety. Here’s how to organize your foods and materials:
Using Lids and Covers
Cover your dishes with microwave-safe lids or wraps to keep moisture in and prevent splatters. Be sure to leave a small gap for steam to escape. Avoid using regular plastic wrap, as it might not be safe in high temperatures.
Containers with Ventilation
Using containers with ventilation is a good practice when microwaving. These containers have small holes that allow steam to escape, reducing the risk of pressure build-up and explosions.
Microwave Cooking Techniques
Now that you know what to microwave, let’s discuss effective techniques for using your microwave.
Stirring and Flipping
Frequently stirring and flipping your food can help it cook evenly. It breaks up hot spots and ensures that the central portions heat up as effectively as the outer edges.
Standing Time
Allowing your food to stand for a couple of minutes after microwaving can also improve results. This resting time lets the heat distribute evenly throughout the dish.
Experimenting with Power Levels
Don’t hesitate to adjust the power levels of your microwave for different foods. For example, cooking dense foods like potatoes on a lower power level can yield better results than blasting them at full power.
Common Mistakes When Microwaving
As convenient as microwaves are, there are still common mistakes people make. Understanding these can vastly improve your microwaving skills:
Not Using Microwave-Safe Containers
One major mistake is not checking whether containers are microwave-safe. Always double-check labeling and avoid using anything that might not withstand microwave radiation.
Overcooking Food
Another common error is overcooking food. Microwaves can heat food quickly, so it’s essential to monitor cooking times. Use a thermometer if you’re unsure whether it is cooked to the proper temperature.
Ignoring Package Instructions
Many pre-packaged foods come with specific mircrowave instructions for a reason. Ignoring these guidelines can lead to unsatisfactory results or even safety hazards.
