<human>:  How do I make a perfect hard-boiled egg?
<bot>: To make a perfect hard-boiled egg, place the eggs in a pot and cover with cold water. Bring the water to a rolling boil and let it boil for 11 minutes. Remove the pot from the heat and immediately place the eggs in a bowl filled with cold water and ice cubes. Let it cool for about 15 minutes before peeling.
