Place the eggs in a pan of water such that they submerge entirely in the water. The water should be an inch above the eggs. Add a few drops of vinegar to the water, to prevent the eggs from cracking. The vinegar tip is optional.
Set the flame on high, and bring the water to a boil. Once the water starts bubbling, lower the flame and allow the eggs to cook. You can time the cooking process, depending on how you want your eggs done. If you want the eggs to be full-boiled, you'll need to cook them for 12-14 minutes. If you want a runny yolk and a soft white or what is called quarter-boiled egg, follow the procedure mentioned above for about 6 minutes. Half-boiled eggs take 8-10 minutes to cook. Here the egg-white is firmer and so is the yolk, but they aren't done entirely.
If you want a full-boiled boil egg, you can know if it is done by checking the level of the water. When the water reduces and covers the egg, you get a quarter-boiled egg. When the water level drops below the egg, and part of the egg shows above the water, you get a half-boiled egg. When the water reduces further, and the egg above the water is about a one-rupee coin, you have a full-boiled egg.
