5.1. Boiling Eggs (Soft, Medium, Hard)

1. Add Water: Use the provided measuring cup to add the appropriate amount of water to the heating plate in the main unit. The measuring cup has markings for soft, medium, and hard-boiled eggs, depending on the number of eggs.

2. Pierce Eggs: Gently pierce the wider end of each egg with the needle located at the base of the measuring cup. This helps prevent cracking during cooking.

6. Automatic Shut-off: The cooker will automatically turn off when all the water has evaporated, thanks to its dry-boil protection.
