A classic Japanese appetizer where the egg is slowly cooked sous-vide. The white becomes silky smooth and the yolk transforms into a rich, creamy gel.

Instructions

  1. Preheat the sous-vide bath to 64°C. Gently lower the eggs into the bath and cook for 45 minutes.

  2. Meanwhile, gently heat the water (or dashi) with the soy sauce and mirin in a small saucepan. Do not let it boil; keep it warm.

  3. Remove the eggs from the bath. Carefully crack each one into a slotted spoon or fine-mesh strainer so the watery part of the white drains away.

  4. Slide the remaining soft egg into a shallow bowl. Pour the warm broth around the egg and garnish with the spring onion and sesame seeds.

💡Tips & Notes

  • Use the freshest eggs you can find; older eggs have a thinner white that drains away too easily.
  • Holding the bath exactly at 64°C is critical; even 1°C makes a noticeable difference in yolk texture.
  • The eggs can hold for up to 60 minutes at 64°C without overcooking, useful when timing the rest of a menu.
  • A light dashi base lifts the dish from a side note to a proper starter; try kombu-bonito dashi.
