Boil a pot of water with plenty of salt and white vinegar.
Have a wooden spoon, small bowl or measuring cup and a slotted spoon on hand.
When the water boils, turn the heat down so there are only a few bubbles coming to the top of the water. With the wooden spoon, stir the water in a circle creating a little whirlpool. Slowly drop the egg into the center of the whirlpool.
