Do u think ,is this a perfect hard boiled egg or not?

The egg we normally use is medium size ,so try that in the below list...unless u bought big size eggs....

Put eggs in pan which fits compactly and fill with water an inch above eggs....
Start to boil, once u see little bubbles all over eggs and when they are ready to boil rapidly....set timer and follow below timings....

don't need to add salt....if it didn't work out properly try next time with salt with same steps....but it will work without salt I guarantee it....
If the egg is cracked then add a tsp of vinegar which will prevent white from running to water..(vinegar will help egg to coagulate,its the reason the white won't spread in water)

Once after timing is done, immediately show in tap cold water and cool it and open shell ....
