To boil eggs in a kettle, follow these steps:

1. Fill the kettle with enough water to cover the eggs by about an inch.

2. Place the kettle on the stove and turn on the heat to high.

3. Once the water reaches a rolling boil, carefully lower the eggs into the kettle using a spoon or slotted spoon.

4. Reduce the heat to a simmer and let the eggs cook for 6-8 minutes for a soft-boiled egg or 10-12 minutes for a hard-boiled egg.

5. Remove the kettle from the heat and let the eggs sit in the hot water for an additional 5 minutes for a soft-boiled egg or 10 minutes for a hard-boiled egg.

6. Drain the eggs and immediately place them in an ice bath to stop the cooking process.

Boiling eggs in a kettle is a convenient and efficient method, especially for those who prefer a stovetop appliance over a dedicated egg boiler. The kettle's large capacity allows for boiling multiple eggs at once, making it ideal for batch cooking. Additionally, the even heat distribution of a kettle ensures that the eggs cook uniformly, resulting in a consistent texture.

According to a study published in the Journal of Food Science, the cooking time for eggs in a kettle can vary depending on the size of the eggs and the desired level of doneness. For example, a large egg will take longer to cook than a small egg, and a soft-boiled egg will take less time than a hard-boiled egg. This highlights the importance of monitoring the cooking time and adjusting it based on the specific requirements of the recipe. Furthermore, the use of a kettle for boiling eggs is cost-effective, as it utilizes an already existing kitchen appliance, thereby reducing the need for additional specialized equipment.
