Work out boiled egg time instantly with clear inputs, formula shown and shareable results.
Times are taken from lowering the egg into already-boiling water: about six minutes for a runny yolk, eight for jammy and eleven for hard, adjusted for egg size and a fridge-cold start. The yolk sets between 65 and 70 C, so a thirty second difference is visible, which is why timing from the boil rather than from cold water is more repeatable.
