Other Requirement:

To make hard boiled eggs, place a few eggs in a saucepan; cover with at least an inch of water, preferable 2 inches. Add a half teaspoon of vinegar and some salt to the water (if the shells crack while boiling, the vinegar will help keep the egg in the shell). Cover the pan and bring the water to a boil. As soon as the water begins to boil, remove the pan from heat and let it sit, covered, for 12 minutes. Drain the water from the pan, add cold water to cool the eggs, let sit a couple minutes longer.
