How long does it take to boil an egg at high altitude?

Click on the egg to calculate the cooking time.


3mins 29secs

This is the time taken to cook a perfect soft-boiled egg if you place the egg directly into a pan of boiling water. It is a slight modification of this work of genius from CDH Williams, combined with a few of the altitude formulae used on this site to provide a handy and practical high-altitude cookery tool.

Have you tried the calculator out? How were the eggs? Email to let us know.
