To boil eggs in a kettle, follow these steps:

1. Fill the kettle with enough water to cover the eggs by at least 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 2-3 minutes.

6. Drain the eggs and 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 not to use a separate pot. According to the United States Department of Agriculture (USDA), the recommended cooking times for eggs are 6-8 minutes for a soft-boiled egg and 10-12 minutes for a hard-boiled egg. This method ensures that the eggs are cooked to the desired level of doneness without the risk of overcooking, which can lead to rubbery or dry yolks. Additionally, using a kettle can save time and energy, as it eliminates the need to transfer eggs from one pot to another. The convenience and efficiency of boiling eggs in a kettle make it a popular choice among busy individuals and families.
