Frequently Asked Questions

How long do you boil eggs for soft, jammy, or hard yolks?

+

Starting in boiling water: 6 minutes for soft-boiled, 7–8 minutes for jammy, 10–12 minutes for hard-boiled. Transfer to an ice bath immediately after to stop cooking.

Should I start eggs in cold or boiling water?

+

Boiling water is more consistent. Starting cold varies with pot size, stove power, and egg count. Lower eggs gently with a spoon into already-boiling water.

Why do hard-boiled eggs get a green ring?

+

Over-cooking causes a harmless iron-sulfur reaction at the yolk edge. An ice bath right after cooking prevents it.

How long are hard-boiled eggs good for?

+

Refrigerated hard-boiled eggs last 7 days in their shells. Peeled eggs last about 5 days in a sealed container.
