Japanese Ramen Eggs (Ajitsuke Tamago)

Instructions

1. 1

   Bring a pot of water to a full rolling boil. Lower eggs gently with a spoon. Boil exactly 6 minutes and 30 seconds for a perfectly jammy yolk — still bright orange and slightly flowing in the center. Start a timer the moment the eggs enter the water.

2. 2

   Transfer immediately to an ice bath and cool for 5 minutes. This stops the cooking instantly and helps the eggs peel cleanly. Peel carefully under cold running water.

3. 3

   Combine soy sauce, mirin, sake, sugar, and water in a small saucepan. Bring to a brief boil, stir until sugar dissolves. Cool to room temperature.

4. 4

   Place peeled eggs in a zip-lock bag or jar. Pour marinade over to cover completely. Refrigerate for at least 4 hours, turning occasionally, up to 3 days. The eggs absorb the marinade and turn a beautiful mahogany brown, with the yolk remaining jammy.

5. 5

   Slice in half lengthwise just before serving. Use in ramen bowls, on rice, or as a snack.
