Ingredients and Tools

  • Fresh eggs (recommended AA grade)
  • 100°C boiling water pot (diameter ≥ 15cm)
  • 30°C warm water pot (diameter ≥ 15cm)
  • Timer
  • Slotted spoon

Measurements

  • Egg 1 (about 60g )
  • 100°C boiling water 1500ml
  • 30°C warm water 1500ml

Steps

  • Prepare two pots of water: Pot A at 100°C boiling water, Pot B at 30°C warm water
  • Use a slotted spoon to place the egg into Pot A, start the timer
  • Precisely every 2 minutes transfer the egg to the other pot
  • Repeat the transfer operation 16 times total (total time 32 minutes)
  • After the final transfer, rest in Pot B for 30 seconds
  • Immediately place into ice water (0 Celsius) to stop heating (maintain for 30 seconds)
  • When peeling, start at the blunt-end air cell and peel the membrane along the longitudinal axis

Notes

  • Key parameters:
  • Yolk center temperature: 67±1°C
  • White layering temperatures:
  • Outer layer: 100°C→87°C
  • Middle layer: 87°C→55°C
  • Inner layer: 55°C→30°C
  • Nutrition advantage: polyphenol content is 23% higher than traditional boiling. If you follow this guide and find issues or processes that can be improved, please submit an Issue or Pull request.
