How long dues it take to boil an egg?

* Soft-boiled: 3-4 minutes

* Medium-boiled: 6-8 minutes

* Hard-boiled: 8-10 minutes

Here are some factors that can affect boiling time:

* Egg size: Larger eggs take longer to cook.

* Starting temperature of the water: Cold water takes longer to heat up.

* Altitude: Water boils at a lower temperature at higher altitudes, so eggs will take longer to cook.

Pro Tip: For perfect hard-boiled eggs, add the eggs to cold water and bring to a boil. Once boiling, turn off the heat and let the eggs sit in the hot water for 10 minutes. This method helps prevent the yolk from becoming green.
