Boiling eggs in a kettle is a practical and efficient method for achieving consistent results. The kettle's large capacity allows for multiple eggs to be cooked simultaneously, making it ideal for batch cooking. Additionally, the even heat distribution of a kettle ensures that the eggs are cooked uniformly, reducing the risk of unevenly cooked yolks or overcooked whites.

The reason for boiling eggs in a kettle lies in the kettle's ability to maintain a steady temperature. Kettles are designed to boil water quickly and maintain a consistent temperature, which is crucial for cooking eggs. According to a study published in the Journal of Food Science, the ideal temperature for boiling eggs is between 160°F and 180°F (71°C to 82°C). Kettles can reach and maintain this temperature range efficiently, leading to a more precise and reliable cooking process. Furthermore, the large opening of a kettle allows for easy monitoring and handling of the eggs, ensuring that they are not overcooked or undercooked.
