Marinated Soft-Boiled Ramen Eggs (Ajitsuke Tamago)
Ajitsuke tamago are those glossy, jammy-yolked eggs sitting in a bowl of ramen that you always want more of. The good news: they're completely manageable at home, and once you nail the soft-boil timing, the rest is just patience while the marinade does its work. The yolk should be set at the edges but still a little wobbly and rich in the center. A 6-minute-30-second boil gets you there reliably, as long as your eggs go straight from the fridge into already-boiling water. The marinade is a simple soy, mirin, and sake mixture, sweet and deeply savory. Give them at least four hours in the fridge, though overnight is where the magic really happens. You'll end up with eggs that are beautifully stained a deep amber on the outside and custardy gold within.
