Soy Sauce Cured Egg Yolks

Pro tips

• Separate yolks carefully with a yolk separator or clean hands over a bowl; any egg white will cloud the brine and affect texture.
• Keep the brine fully submerged by covering yolks with a small piece of parchment or plastic wrap weighted down with a small dish to prevent air exposure.
• Check at day 2 for firmness: they should be jelly-like, not runny. Refrigerator temperature affects curing speed.
• Use a shallow, wide container so yolks sit in even depth of brine and cure uniformly.

Substitutions

• Rice vinegar → Apple cider vinegar (adds slight sweetness; reduce by 1 tbsp for balance)
• Chinese five spice → 1/4 tsp white pepper + 1/4 tsp ground Sichuan pepper (more peppery, less warm spice)
• Ground ginger → 2-3 thin slices fresh ginger (milder, fresher note)

Storage & make-ahead

Store cured egg yolks in their brine in an airtight container in the refrigerator for up to 2 weeks; they firm further over time and do not need reheating.

How long do cured egg yolks take to cure?

Cured egg yolks typically cure in 3 days in the refrigerator. The yolks will firm up slightly around the edges while remaining jelly-like in the center.

Can I use regular vinegar instead of rice vinegar?

Rice vinegar is milder and less acidic than white vinegar, so substituting may make the brine too sharp. Stick with rice vinegar for the intended balance.

How long do cured egg yolks keep?

Store in their brine in an airtight container in the refrigerator for up to 2 weeks. The longer they sit, the firmer they become.

What soy sauce works best?

Use a quality soy sauce (Japanese shoyu or Chinese soy sauce both work). Avoid low-sodium varieties, which won't develop the same umami depth.

Can I scale this recipe up?

Yes. Maintain a 2:1 ratio of soy sauce to rice vinegar and 1/2 tsp of spices per 6 yolks to keep flavors balanced.
