The recommended boiling time for eggs in a Skyline Egg Cooker is typically around 6 to 8 minutes for a soft-boiled egg and 10 to 12 minutes for a hard-boiled egg. This duration ensures that the eggs are cooked to perfection without overcooking, which can lead to rubbery textures.

The reason for these specific times lies in the design of the Skyline Egg Cooker. This appliance uses a water bath to cook the eggs, which provides a consistent and even heat distribution. The cooking time is influenced by the egg's size and the desired level of doneness. A soft-boiled egg is cooked for a shorter period to maintain a runny yolk, while a hard-boiled egg requires a longer cooking time to solidify the yolk and white. According to the Skyline Egg Cooker's user manual, the recommended times are based on extensive testing and are designed to achieve the ideal balance of texture and flavor. Additionally, the American Egg Board suggests that cooking eggs for too long can result in a loss of nutrients and a less appealing taste, further emphasizing the importance of adhering to the recommended cooking times.
