I usually have an egg daily for breakfast - quite often coddled (a nicer method than boiling it), although sometimes poached or scrambled.
To coddle the egg, I pierce the wider end of the egg with a skewer (to allow the air to escape and so not break the egg) and bring water to the boil. Then I place the egg in (with a teaspoon) and lower the heat to medium, letting it simmer for 1 minute.
Then leave it in the pan but off the heat for 4 mins. The perfect soft egg with velvety egg white, i.e. not tough.
I eat it with sourdough toast and organic butter.
