EGG TIMER
Perfect boiled eggs every time. Soft, medium, or hard , you choose.
EGG TIMER ONLINE
Boiling an egg is one of the simplest cooking tasks, yet most people get inconsistent results because they estimate time instead of measuring it. The difference between a soft-boiled egg with a liquid yolk and a hard-boiled egg with a dry, chalky yolk is just 4 to 5 minutes of additional cooking. This egg timer provides presets calibrated to standard egg sizes at room temperature and from refrigerator temperature, eliminating guesswork. At 100 degrees Celsius, egg white proteins begin denaturing at 62 degrees internal temperature (around 2 minutes of boiling for a large egg). The yolk starts setting at 68 degrees (about 6 minutes) and becomes fully solid at 77 degrees (10 to 12 minutes). These are narrow windows where even 30 seconds matters. The timer includes guidance for soft (3 minutes), medium (6 minutes), and hard (10 minutes) boiled results, adjusted for egg size.
How It Works
Select your preferred doneness level: soft boiled (runny yolk), medium boiled (jammy yolk), or hard boiled (fully set yolk). The timer sets the appropriate duration based on standard cooking science. Press Start after placing your eggs in boiling water. The countdown displays remaining time with a progress ring. When the alarm sounds, transfer your eggs immediately to an ice bath to stop cooking. Adjust the time with +/- buttons for different egg sizes or starting temperatures.
When to Use This Timer
Use the soft preset (3 minutes) for ramen-style eggs with liquid yolks. Set the medium preset (6 to 7 minutes) for jammy eggs perfect in salads and grain bowls. The hard preset (10 to 12 minutes) produces fully set eggs ideal for deviled eggs, egg salad, and travel snacks. Meal prep sessions benefit from timing a full batch of eggs with precision rather than guessing.
The Science of Egg Protein Denaturation
Egg whites contain ovalbumin, which denatures (changes from liquid to solid) between 62 and 65 degrees Celsius. Egg yolks contain different proteins that denature between 68 and 77 degrees. Because the yolk is insulated by the white, it reaches these temperatures several minutes later than the white. This temperature gap is why precise timing controls the exact consistency: a few minutes either way shifts the yolk from liquid to jammy to chalky.
Frequently Asked Questions
How long for a soft-boiled egg?
For a large egg at room temperature in boiling water: 3 minutes produces a liquid yolk with set whites. For refrigerator-cold eggs, add 30 seconds. Place eggs directly into already-boiling water, not cold water brought to a boil, for consistent results.
Why should I use an ice bath after boiling?
An ice bath immediately stops carryover cooking. Without it, residual heat in the egg continues raising the internal temperature for several minutes, potentially pushing a perfect medium egg into hard-boiled territory.
Does altitude affect boiling time?
Yes. Water boils at lower temperatures at higher altitudes (approximately 95 degrees Celsius at 5,000 feet). At high altitude, add 1 to 2 minutes to each preset to compensate for the lower cooking temperature.
Can I boil eggs starting from cold water?
Yes, but timing is less precise because the heating phase varies by stove power and water volume. The cold-start method adds approximately 3 to 4 minutes to total time. For consistent results, the boiling-start method with this timer is more reliable.
What is a jammy egg?
A jammy egg has a yolk that is partially set around the edges but soft and creamy in the center, with a custard-like consistency. It typically requires 6 to 7 minutes of boiling for a large egg. This texture is prized in ramen, on toast, and in salads.
