Setup
- Unpack: Carefully remove all packaging materials and ensure all components are present.
- Clean: Before first use, wash the transparent lid, egg holder, and measuring cup in warm, soapy water. Rinse thoroughly and dry. Wipe the heating plate with a damp cloth. Do not immerse the base unit in water.
- Placement: Place the egg cooker on a stable, flat, heat-resistant surface, away from water sources and other heat-generating appliances.
Operating Instructions
Follow these steps for perfect eggs:
- Prepare Eggs: Using the integrated egg piercer on the bottom of the measuring cup, carefully pierce a small hole in the larger end of each egg. This helps prevent cracking during cooking.
- Add Water: Use the measuring cup to add the appropriate amount of water to the heating plate. The amount of water determines the doneness of the eggs (soft, medium, or hard). Refer to the markings on the measuring cup for guidance. The water reservoir capacity is 100 ml.
- Place Eggs: Place the egg holder onto the heating plate. Position up to 7 pierced eggs into the egg holder.
- Cover: Place the transparent lid securely over the egg holder and base unit.
- Select Doneness: Turn the control knob to your desired doneness setting (soft, medium, or hard). The appliance features a timer for these settings.
- Start Cooking: Plug the appliance into a suitable power outlet. Press the On/Off switch. The indicator light will illuminate, signaling that the cooking process has begun.
- Audible Signal: Once the water has evaporated and the eggs are cooked to the selected doneness, an audible signal will sound, and the appliance will automatically shut off.
- Remove Eggs: Carefully unplug the appliance. Using oven mitts or a cloth, remove the transparent lid. Be cautious of hot steam. Lift the egg holder by its handles and immediately rinse the eggs under cold water to stop the cooking process and make them easier to peel.
