The most common form of scoliosis is idiopathic scoliosis. Unfortunately, in this case, there is no obvious cause. The condition may be inherited, but that theory is still being tested.
Step 1: The Boiling Stage. Put up a pot of water to boil â you'll need one big enough for water to flow freely around the number of eggs you'll be cooking. Once the water's boiling, use a large spoon to gently lower the eggs into the water. Lower the heat to maintain a simmer and set a timer for 12 minutes. Now, don't stress...if you let the water boil a little too much or drop below a simmer or fish out your eggs 14 minutes later, it's okay.
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.
