A widely known tip
Verification: Supported by evidence
AI verification reports the evidence it found; it does not guarantee that a claim is true.
Plunging eggs into ice water right after boiling makes the contents shrink, opening a gap between the shell and the membrane, so they peel more easily.
Evidence
Secondary A food scientist's explanatory article. Quenching boiled eggs in ice water makes the white shrink slightly away from the shell, so they peel more easily link
Secondary A dietitian's explanatory article. Its headline says that rapid cooling after boiling makes eggs even easier to peel link
Notes and limits
The study in which "the effect disappeared in eggs stored for a long time" was about adding salt to the boiling water, not about rapid cooling (the article in source 1). Whether the effect of rapid cooling depends on the age of the egg has not been checked.
