Boiling is a cooking method where a liquid, usually water, is heated until it reaches a temperature of 100 degrees Celsius (212 degrees Fahrenheit) at sea level. At this point, bubbles form and rise to the surface, creating a rolling boil. This process is commonly used for cooking foods like pasta, vegetables, and eggs, ensuring they are cooked thoroughly and evenly. When boiling, it's important to monitor the heat to avoid overcooking or spilling. Adding salt to the water can enhance the flavor of the food, while using a lid can help the water boil faster. Boiling is a simple yet effective way to prepare meals quickly and efficiently.
