There are a couple of ways to boil an egg. The way I do it is;
Put eggs into a pan of cold water, until the eggs are completely covered, and put on the cooker at the highest heat. Some people add salt as they believe this stops the shell from cracking. Once the water starts to boil time it for 3 minutes then take the eggs out of the pan and open them up and eat with your toast!
There are other ways so feel free to add to this.
