Understanding Microwave Cooking
Before we dive into the specifics of using a wet paper towel, it’s essential to understand how microwave cooking works. Microwave ovens use non-ionizing radiation, called microwaves, to heat and cook food. These microwaves penetrate the food and cause the water molecules within it to vibrate rapidly, generating heat through dielectric heating. This process allows for rapid heating, but it can also lead to uneven cooking, as the microwaves may not penetrate uniformly, especially in thicker or more dense foods.
The Role of Moisture in Microwave Cooking
Moisture plays a critical
role in microwave cooking. Water molecules are excellent absorbers of microwave energy, which is why foods high in moisture content tend to heat more evenly and quickly.
