Egg boiling guide for soft, jammy, and hard yolks

Achieving consistent results when boiling eggs depends on controlling variables such as egg size, starting temperature, and the method used. To ensure precision, it is recommended to bring water to a rolling boil before gently adding the eggs, rather than starting them in cold water. Timing should begin the moment the eggs are placed in the boiling water.

For medium-sized eggs at room temperature, soft yolks are typically achieved around 4.5 to 6 minutes, while jammy or semi-soft yolks require approximately 7 to 8 minutes. Fully hard-boiled eggs generally take between 10 and 12 minutes. Larger eggs typically require an additional 30 to 45 seconds per stage, whereas smaller eggs may require slightly less time.

To prevent overcooking, eggs should be rinsed in cold water immediately after the timer expires. Variations in stove heat, pot size, and water volume can influence the final result, so maintaining a consistent routine is key to repeatable outcomes.
