Standard US/EU egg sizes by weight. Choose Custom to enter an exact weight.
Fridge eggs need roughly 1 extra minute compared to room-temperature eggs.
Water boils at a lower temperature at higher altitudes, so eggs take longer. Enter 0 for sea level.

Soft (runny yolk) egg: boil for 12 min 11 sec.

  • Your egg is coming straight from the fridge (4 C). Room-temperature eggs cook about 1 minute faster.
  • Lower the egg gently into already-boiling water on a spoon to avoid cracking, then start the timer.
  • Transfer to ice water immediately after boiling to stop carry-over cooking and make peeling easier.

Next stepFor the most consistent results, use a digital kitchen timer and an ice bath ready before the eggs go in.
