How to Make Half Boiled Egg

My older daughter loves to eat half boiled egg. Everyday she eats 1 egg.

This is how I make it:

Boil the water in the pan.
After the water boil, put the egg in. Then let it boil for exactly 2 minutes. Remember this egg is cold egg from fridge, if the egg is not cold than only boil for 1 minutes.
