An egg cooker is a kitchen appliance designed to simplify the process of cooking eggs. It can prepare eggs in various styles, such as hard-boiled, soft-boiled, or poached, by using steam or boiling water. Most models come with a tray that holds multiple eggs and a measuring cup to ensure the right amount of water is used for the desired doneness. Using an egg cooker is straightforward. Users typically add water to the base, place the eggs in the tray, and turn the appliance on. The cooker automatically shuts off when the eggs are done, making it a convenient option for busy individuals or families.
