Instructions
- Gather Equipment
Gather 4 eggs, salt, and cold water; set out a pot, lid, timer, colander, bowl, and serving plate near the sink. · 2 min

- Cover Eggs
Place the eggs in one layer in the pot, cover with 1000 ml cold water, add salt, and set the pot over medium heat. · 3 min
What to look for: Eggs sit fully submerged with water about 2 cm above them.
- Bring To Boil
Bring the water to a boil, then reduce the heat at once until only small, steady bubbles rise around the eggs. · 6 min
What to look for: Water reaches a rolling boil, then settles to a gentle simmer.
- Simmer Eggs
Simmer the eggs for 9 minutes, keeping the bubbles gentle; avoid passing 10 minutes to prevent a grey-green yolk ring. · 9 min
When it is done: Yolk is fully set after the timed 9-minute simmer.
- Cool Quickly
Drain the hot water carefully, then rinse the eggs immediately under cold running water to stop cooking. · 2 min
What to look for: Steam fades and the shells feel cool enough to handle.
- Peel Shells
Crack each shell lightly on the counter, then peel under cold water so the shell slips away cleanly. · 3 min

- Serve Eggs
Serve the peeled eggs warm or chilled, whole or halved, with firm whites and fully set yellow yolks. · 1 min
What to look for: Eggs look clean, smooth, and evenly cooked.

Ingredient substitutions
Egg
- Large egg: Use the same method, checking that the yolk is fully set without exceeding 10 minutes.
Water
- Filtered water: Use enough cold water to cover the eggs by about 2 cm.
Salt
- Fine salt: Use slightly less fine salt because it packs more densely than coarse salt.
