The standard time to boil eggs in an egg cooker is approximately 7 to 10 minutes. This duration is sufficient for hard-boiled eggs, which are the most common type of eggs cooked in an egg cooker. The precise cooking time can vary slightly depending on the model of the egg cooker and the desired level of doneness. For example, if you prefer your eggs to be slightly undercooked, you may need to reduce the cooking time to around 6 minutes. Conversely, if you prefer a fully cooked, hard-boiled egg, you can extend the cooking time to 10 minutes.

The reason for this relatively short cooking time lies in the design of the egg cooker. These devices are specifically designed to maintain a consistent water temperature, typically around 212°F (100°C), which is the boiling point of water at sea level. This controlled environment ensures that the eggs are cooked evenly and quickly. Additionally, the eggs are submerged in water, which allows for even heat distribution and prevents the eggs from sticking to the bottom of the cooker.

According to a study published in the Journal of Food Science, the cooking time for hard-boiled eggs in an egg cooker is significantly shorter than traditional boiling methods, such as placing eggs in a pot of boiling water. This is because the direct heat from the stove can cause the eggs to cook unevenly and may result in a longer cooking time. Furthermore, the use of an egg cooker can prevent the eggs from cracking or breaking during the cooking process, which can also contribute to a longer cooking time if the eggs are being boiled in a pot.

In summary, boiling eggs in an egg cooker typically takes between 7 to 10 minutes, depending on the desired level of doneness and the specific model of the cooker. This method is efficient and ensures even cooking, thanks to the controlled water temperature and the design of the egg cooker itself.
