📝 Instructions

7 steps
1

Fill a large pot with 2 liters of water. Over medium heat, warm the water to exactly 70°C (158°F) using a kitchen thermometer for accuracy.

2

While the water is heating, prepare a bowl of ice water and set it aside.

3

Once the water reaches the desired temperature, gently add the eggs to the pot using a spoon to prevent cracking.

4

Maintain the temperature at 70°C (158°F) by adjusting the heat as necessary. Allow the eggs to cook for 30 minutes.

5

After 30 minutes, use a slotted spoon to transfer the eggs into the prepared bowl of ice water. Let them cool for 5 minutes to stop the cooking process.

6

Carefully crack the eggs into individual small bowls to serve. The yolk should be creamy and the white should be just set.

7

These onsen eggs can be served immediately as-is or used to top dishes like rice, ramen, or salads for added flavor and texture.
