Soy-Cured Egg Yolks

Pro tips

• Separate yolks carefully over a bowl to avoid any white; even small amounts can dilute the brine and affect texture.
• Let the yolks cure for at least 3–4 days for optimal jammy texture and flavor absorption; up to 7 days deepens the umami.
• Keep yolks submerged in brine by using a small glass or ceramic dish and covering tightly to prevent oxidation and ensure even curing.
• Reserve leftover brine after serving yolks—it can be used as a dipping sauce or drizzled over rice for extra flavor.

Substitutions

• Light soy sauce → tamari or shoyu (dark soy sauce will darken the cure and add sweetness)
• Mirin → hon-mirin or aji-mirin (shio-koji can replace both for deeper umami, though flavor profile shifts)

Storage & make-ahead

Store cured yolks in an airtight container submerged in brine in the refrigerator for up to 10 days; serve cold or at room temperature.

How long do soy-cured egg yolks last in the refrigerator?

Stored in an airtight container, they keep for up to 7–10 days in the brine.

Can I use dark soy sauce instead of light soy sauce?

Dark soy sauce will work but will create a darker, slightly sweeter cure; light soy sauce is recommended for the traditional result.

Do the egg yolks need to be raw when curing?

Yes, raw yolks are essential—they develop a jammy, custard-like texture as they cure in the brine.

What dishes work best with soy-cured egg yolks?

They pair beautifully with steamed rice, ramen, udon, soba noodles, congee, and avocado toast for an umami boost.

How do I separate egg yolks cleanly?

Crack the egg gently and transfer the yolk between shell halves, letting the white fall into a bowl, then place the yolk in a separate container.
