Cooking eggs to perfection has never been easier. Yolk is the scientifically based egg timer that calculates the ideal cooking time for your egg, using validated data from research on heat transfer in egg cooking.
Unlike a regular kitchen timer, Yolk takes into account the variables that really matter when it comes to egg doneness: egg size, starting temperature (chilled or room temperature), and the altitude of your location, adjusting the cooking time to ensure the right result wherever you live.
With Yolk you can choose:
Egg size: medium, large, extra, or jumbo
Starting temperature: chilled (refrigerator) or room temperature
Altitude of the location, manually selected for a more precise calculation
Cooking point: soft yolk, creamy yolk, cooked yolk, or hard yolk
Each point was designed for real-world kitchen use: the soft yolk is perfect for dipping toast, the creamy yolk leaves the yolk partially runny, ideal for sandwiches and bowls, the cooked yolk balances firmness with creaminess, and the hard yolk is just right for salads and lunchboxes, without that grayish-green ring around the yolk.
The app calculates the ideal cooking time in seconds, with a visual and easy-to-use kitchen timer — no guessing, no testing, no raw or overcooked eggs.
