Instructions
- 1
Bring a large pot of water to 167°F — use a thermometer. This precise temperature is critical: the whites set at a lower temperature than the yolk, creating the characteristic custard-soft white with a still-liquid yolk. A water that's too hot gives a fully cooked egg; too cool leaves the white unset.

Lower eggs gently into the 167°F water. Maintain the temperature carefully — this may require adjusting the burner between low and medium. Cook for exactly 13 minutes.
- 3
Transfer eggs immediately to cold water for 1 minute to stop cooking. The eggs can be refrigerated in their shells for up to 3 days.

Make tsuyu: combine dashi, soy sauce, mirin, and sugar in a small saucepan. Heat until sugar dissolves. Cool to warm.

To serve: crack each egg into a small bowl. The white should be softly set and cloud-like, the yolk liquid and golden. Pour 3 tablespoons tsuyu over each egg. Top with green onion and katsuobushi. Serve with a small bowl of steamed rice for the egg to rest on.
