The Japanese ramen egg technique (ajitsuke tamago) elevates a simple soft-boiled egg into an umami delivery device. After shocking and peeling 6-minute-and-30-second eggs, place them into an airtight container or a zip-top bag with a simple curing marinade:

• 4 parts water or dashi
• 2 parts Japanese soy sauce (shoyu)
• 2 parts mirin (sweet rice wine)
• 1 part unseasoned rice vinegar or sake

Submerge the peeled eggs for 4 to 12 hours in the refrigerator. A folded paper towel placed on top of the liquid keeps floating eggs fully coated. The salt in the soy sauce cures the outer layer through osmosis, deepening the golden hue and transforming the jammy core into a rich, spreadable paste.
