First-Time Setup

Cooking Perfect Eggs

- Assemble and cook: Place the egg holder into the device, then put on the lid.

- Listen for the signal: When the eggs are ready, the device will emit an acoustic signal and a voice prompt will announce the doneness level. The device will then shut off automatically.
- Cool and serve: Remove the lid carefully to avoid steam burns. Lift out the egg holder and run the eggs under cold water to stop the cooking process and make them easier to peel.
