Instructions
1Wash the eggs
Add salt to the eggs and scrub them gently to ensure they are thoroughly cleaned before cooking.
Tip: Using a gentle scrub pad helps remove any debris from the shells effectively.
2Boil the eggs
Bring a pot of water to a boil, then carefully add the eggs. Boil for exactly six and a half minutes to achieve the perfect soft-boiled texture.
Tip: Using a timer is crucial to getting the yolk consistency just right.
3Chill the eggs
Immediately after boiling, transfer the eggs into a container filled with ice water to stop the cooking process.
Tip: The ice bath is essential to prevent overcooking and makes peeling much easier.
4Peel the eggs
After cooling the eggs in ice water for ten minutes, gently use the back of a spoon to crack and remove the eggshells.
Tip: Cracking the shell under the water can help loosen it for easier peeling.

Yes, for a jammy but slightly firmer yolk, increase the boiling time to 7 minutes. For a fully set yolk, 9 to 10 minutes is recommended.
Salt acts as a mild abrasive to help clean the surface of the shell, ensuring no debris ends up in your water, though plain water scrubbing is also effective.
