How long do I boil an egg?

From cold water, brought to a boil: 4 minutes for runny yolk, 6 for jammy, 8 for fully set but still bright, 10 for hard-boiled. Drop into ice water immediately to stop cooking and make peeling possible. Older eggs peel easier than fresh.

Follow-up questions

Why are my eggs hard to peel?

Eggs less than a week old grip their shell. Use older eggs, or steam them instead of boiling — steamed eggs peel beautifully.

How long for soft-boiled?

6 minutes from a rolling boil if you drop the eggs in (room temperature). 3 minutes from cold-water start brought to boil and removed off heat.

Can I tell if an egg is bad?

Float test: place in a bowl of water. Sinks and lies flat — fresh. Stands upright — old but fine. Floats — throw it out.

Why won't my egg peel?

Too fresh — older eggs (1–2 weeks) peel cleanly. Steaming works even for fresh.

Does adding vinegar help?

Slightly — helps whites set fast if a shell cracks. Doesn't affect peeling much.
