Microwave cooking uses electromagnetic waves to heat food quickly and efficiently. The microwave oven generates these waves, which excite water molecules in the food, causing them to vibrate and produce heat. This method allows for faster cooking times compared to traditional ovens. Microwave cooking is versatile and can be used for reheating leftovers, cooking meals, or even defrosting frozen items. Many microwave-safe containers are available, ensuring that food is heated evenly and safely. However, it's important to follow guidelines for cooking times and power levels to achieve the best results.
