Timing matters here. Too few minutes and the yolk remains runny; too many and the chemistry inside the egg begins to work against you — which is precisely what the next step is designed to prevent.
The ice bath: why skipping it ruins the yolk
Immediately after the 11-minute rest, the eggs are transferred into a bowl of ice water. This step — known as an ice bath shock — stops the cooking process instantly by dropping the egg’s internal temperature in seconds.

Without it, residual heat continues to cook the egg even after it leaves the stove. The result is a visible gray-green ring around the yolk. The recipe explains the chemistry clearly: that ring forms «when the iron in the yolk reacts with the sulfur in the white due to residual heat.»
The ice bath solves both problems at once. It guarantees «a bright, golden, creamy yolk» and causes the shells to «slip right off» during peeling — a practical bonus that makes prep noticeably faster and cleaner.
Choline and brain health: the nutritional case for eating eggs regularly
Beyond flavor, the recipe makes a specific nutritional argument for eggs: they are «one of the best natural sources of choline.» Choline is a nutrient the brain uses to build cell membranes and produce neurotransmitters — the chemical messengers that allow brain cells to communicate.

Adequate choline intake is associated with cognitive function and circulatory health, making eggs a particularly relevant food for older adults monitoring their brain health. The recipe frames eating eggs as «literally like building a shield for your mind.»
