How to boil the perfect egg
Bring your eggs to room temperature before cooking – this prevents the shells from cracking when the water boils.
Place the eggs in a saucepan; cover with cold water and bring to the boil over medium heat. Reduce heat to a simmer – cooking the eggs in hard-boiling water will cause the whites to turn rubbery.
For runny, soft-boiled eggs, cook for three minutes once simmering; for medium eggs with a semi-firm yolk, cook for four minutes.
Remove eggs from the water or they will continue to cook. Serve immediately.
For hard-boiled eggs, cover with cold water and bring to a simmer over medium heat. Cook for six to seven minutes.
Use a slotted spoon to remove and cool under cold, running water. Allow to sit in cold water for two minutes before serving.
