For a hard-boiled egg, start the egg in cold water and bring up to the boil. Once the water is gently boiling, set the timer for between 7-10 minutes depending on how well cooked you like your eggs. The longer you boil the egg, the firmer it will be. Once cooked, plunge the hard-boiled egg into plenty of cold water for one minute. Drain and cover with more cold water.
