how to boil eggs

The most reliable method is to lower eggs into boiling water, simmer for your desired time, and then immediately transfer them to an ice bath.

Start with boiling water. Bring water to a boil, then gently lower the eggs into the pot. Using a slotted spoon helps prevent cracking. Reduce the heat to a gentle simmer to keep the eggs from bouncing and breaking.
Follow precise timing. Timing depends on your preference: 6 minutes for runny yolks, 8 minutes for jammy or soft-boiled, and 10 to 12 minutes for fully hard-boiled eggs. Adjust slightly for egg size.
Use an ice bath. Immediately move cooked eggs to a bowl of ice water for at least 5 to 10 minutes. This stops the cooking process and helps the membrane separate from the shell.
Peel under water. Gently crack the shell all over, starting at the wider end where the air pocket is. Peeling under cool running water or submerged in a bowl of water helps the shell slip off cleanly.
