Frequently asked questions

Does this account for altitude?

No, this is a general estimate. At high altitudes, water boils at lower temperatures, so you may need to increase the time slightly.

Should I start timing when the water boils or when I put the eggs in?

Start timing after the water returns to a rolling boil with the eggs in the pot.

Tips and common mistakes

Tips

  • Use a timer and start it when the water boils.
  • For easier peeling, cool eggs in ice water immediately after boiling.
  • Adjust times by 1 minute if you prefer a softer or firmer yolk.

Common Mistakes to Avoid

  • Starting the timer before the water boils.
  • Using the same time for different egg sizes.
  • Overcooking, which causes a green ring around the yolk.

Assumptions and limitations

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
