Salt-Cured Egg Yolks
Salt-cured yolks are created by burying fresh egg yolks in a mixture of salt and sugar, drawing out the moisture over several days until they firm into a dense, grateable ingredient that adds a concentrated depth to pasta, salads, or roasted vegetables.
Patience is your primary ingredient.
The yolks need time to dehydrate completely in the refrigerator; rushing this will leave them pasty rather than firm.

The Salt-Sugar Barrier
The ratio of salt to sugar creates an osmotic environment that extracts liquid from the yolk while firming the protein structure without over-salting the interior.
The method.
Prepare the bed
Whisk the salt and sugar together until uniform. Spread half of this mixture into the bottom of your container, creating a flat, even layer.
Nest the yolks
Use a spoon to create six shallow indentations in the salt mixture. Carefully place one yolk into each divot. Ensure the yolks do not touch each other or the sides of the dish.
Bury the yolks
Gently pour the remaining salt mixture over the yolks, ensuring they are completely covered by at least half an inch of the mix.
Cure
Cover the dish and place it in the refrigerator for 4 to 5 days. The salt will become visibly damp as it draws moisture out.
Clean and dry
Carefully lift each yolk from the salt. Gently brush off excess grains with a soft brush. If they feel tacky, set them on a wire rack in the fridge for an additional 12 hours.
When it doesn't go to plan.
Always use the freshest eggs possible for this process.
If a yolk breaks during separation, discard it; a ruptured membrane will not cure properly.
Store the finished, firm yolks in an airtight jar in the refrigerator for up to three weeks.
The ones that keep coming up.
Can I reuse the salt mixture?
No. The mixture will contain moisture and proteins from the eggs, which can spoil if kept.
How do I know when they are ready?
The yolks should feel firm, like a hard cheese, and have a deep, translucent amber color throughout.
