An egg steamer is an appliance designed to cook eggs by steaming them, as opposed to boiling them in water. The main advantage of steaming over boiling is that it can result in eggs that are easier to peel and more consistently cooked. Egg steamers typically have trays to hold eggs and a water reservoir that turns into steam. Once the water heats up, the steam gently cooks the eggs. These steamers usually have settings for soft, medium, or hard-boiled eggs and can cook multiple eggs at once. The appliance is known for being quick, energy-efficient, and easy to clean.
