YOLK ATLASRAMEN EGG GRADIENT01 / THE ANATOMY OF A PERFECT EGG
A small atlas of extraordinary textures.
Choose the yolk. Discover your egg.
02 / SPECIMEN LIBRARY
One egg. A spectrum of possibilities.
Select a specimen to examine its texture.
Seven AI-generated food images illustrate different textures. They are visual references, not matched cooking trials or a validated time chart.
03 / THE DIFFERENCE IS IN THE CENTER
Choose any two textures.
Reveal the difference, edge to center.
30-second duel protocol: keep all conditions identical and remove the second egg 30 seconds later. No matched photographic trial is available yet; this comparison demonstrates the interface only.
04 / REVERSE EGG FINDER
Start with the center you love.
Keep your kitchen conditions alongside it.
COOKING ESTIMATE
ESTIMATE · FIRST-TRIAL GUIDANCE
Exploration range: 06:30–08:30
Jammy · medium (about 55 g) · refrigerated (about 4°C)
A starting estimate, not a tested recipe or a food-safety guarantee. The range is a ±60-second exploration window, not a statistical confidence interval. Actual texture can fall outside this window.
Fast cooling is the reference method used to interpret the target texture.
Texture is not a safety test. FDA advises firm yolks and whites, and pasteurized eggs for recipes served raw or undercooked. A soft target may also leave the white incompletely set. FDA guidance ↗
Local size labels are model categories, not national egg grades: small ≈45 g, medium ≈55 g, large ≈65 g (shell-on mass). Start settings mean refrigerated ≈4°C or room temperature ≈20°C. Use the matching setting for the actual egg; warming eggs is not required.
| Target | Baseline |
|---|---|
| Liquid | 05:00 |
| Silky | 05:30 |
| Jammy | 06:30 |
| Custard | 07:00 |
| Creamy | 08:00 |
| Set | 09:00 |
| Firm | 10:00 |
Estimate = baseline + size adjustment (small −30 s; medium 0; large +30 s) + starting-temperature adjustment (4°C +60 s; 20°C 0). These seven texture mappings and offsets are editorial approximations, not a validated heat-transfer or Salmonella model.
Guides disagree on exact timings. Great British Chefs describes boiling-water timing for room-temperature eggs and longer cooking for larger or cold eggs; Good Food provides a texture timing guide and size adjustments. They inform the starting range, not validation of this calculator or the AI images. Great British Chefs ↗ · Good Food ↗
Not calibrated for high elevations, pressure cookers, steam-only cooking, cold-water starts, frozen or extra-large eggs, crowded pots, or a slow return to boiling. Stove, pan, water volume, cooling and egg variation can shift the result by more than a minute. AI-generated images are visual targets, not measured outcomes.

PREFERENCE COORDINATES · NOT A RECIPE06 / FIELD NOTES
Good references begin with honest conditions.
Record egg mass, starting temperature, water volume, heating method, altitude, time in water, cooling method and cooling duration. Photograph the cut surface under the same light and camera angle. Change one variable at a time.
Log cooking and marinating separately. A darker white is not proof of a firmer yolk. Note soy-sauce dilution, refrigeration and marinating duration without treating color as a reliable salt or safety test.
A cracked shell, off-center yolk or dry edge is worth recording. Note what changed and repeat the same setup before drawing conclusions. The atlas uses AI-generated visual references, not measured food experiments.
The displayed time is a first-trial estimate based on texture, size and starting temperature. It is not a matched cooking experiment, and the ±60-second range is not a confidence interval. Start in boiling water, cool promptly, record the result and calibrate for your kitchen.
No. This is a visual preference tool, not a food safety test. FDA advises cooking both yolk and white until firm, and using pasteurized eggs for dishes served raw or undercooked. FDA egg safety guide ↗
