How it is computed

  1. 1基准（M 号·室温·平原）= 6 分钟
  2. 2蛋重修正 = (50 − 50) ÷ 10 = +0.0 分钟
  3. 3冷藏蛋 +1 分钟（下锅前约 4°C）
  4. 4平原 +0 分钟
  5. 5合计 ≈ 7.0 分钟
  • This table times from when the water re-boils after the egg goes in. If you start from cold water, add ~3–4 min to reach a simmer, then time as usual.
  • Rolling boil then 30s gentle simmer keeps yolks centered; stir the first minute so the yolk does not stick to one side.
  • Ice-water bath for 1 min after boiling: stops cooking and makes peeling much easier.
  • Greenish ring on the yolk = overcooked (iron sulfide). Harmless, but taste gets powdery — keep hard-boiled ≤ 13 min.
  • Soft yolks carry a small salmonella risk. Pregnant women, infants and elderly should choose fully boiled eggs; use very fresh eggs for soft style.
  • Very fresh eggs (≤3 days) stick to the shell when peeling — 3–5 days old eggs peel best.
