"A cured yolk is a yolk that decided to become something more useful.

What Curing Does to an Egg Yolk
Salt draws moisture from the yolk through osmosis, concentrating fat and protein into a dense, firm disc. The yolk transforms from a fragile liquid into something that firms enough to handle, slice, and eventually grate. The flavor intensifies — deeply savory with a richness that echoes bottarga or Parmesan. A one-week cure in a 1:1 salt-sugar mixture is the standard starting point.

Make the Cure Bed
Mix equal parts salt and sugar and spread half in the bottom of a dish.
Make the Cure Bed
Combine equal parts fine salt and granulated sugar — 100g of each for up to 6 yolks. Pour half the mixture into a shallow dish or container. Use a spoon to press small indentations into the cure bed — one per yolk. The indentations keep the yolks from rolling and ensure the cure contacts the bottom of each yolk evenly.
Nestle Yolks and Cover
Carefully separate yolks, place in wells, and cover completely with remaining cure.
Nestle Yolks and Cover
Separate eggs carefully — even a small amount of white will cause the yolk to cure unevenly. Lower each yolk into a well using a spoon. Cover completely with the remaining cure mixture, making sure no yolk is exposed. Cover the dish with plastic wrap and refrigerate. The cure will immediately begin drawing liquid from the yolks.
Cure for 7 Days
Refrigerate undisturbed for 7 days — no checking until day 7.
Cure for 7 Days
Leave undisturbed in the refrigerator for 7 days. The cure will become wet and syrupy as it draws moisture from the yolks. At day 7 uncover and gently brush the cure from each yolk — they will be firm, glossy, and amber in color. They should feel like a firm cheese, not squishy. If still soft, re-cover and cure 2 more days.
Dry in the Oven
Rinse briefly, pat dry, and dry in oven at lowest temp for 30 minutes.
Dry in the Oven
Gently rinse each cured yolk under cold water and pat completely dry. Place on a wire rack over a baking sheet. Set the oven to its lowest temperature — around 175°F. Dry for 30 minutes. This step firms the exterior and removes surface moisture. Cool completely before storing in the fridge between layers of parchment.
What You Need
6 fresh egg yolks — the freshest available
100g fine salt
100g granulated sugar
Shallow dish or container
Wire rack for oven drying
Yolk Quality Matters Enormously Fresher eggs produce a more vibrant, uniform cure. Market eggs with bright orange yolks from pasture-raised hens cure into something dramatically better than pale commercial yolks. The cure does not fix a weak yolk — it amplifies what is there.
"Grate one over a bowl of pasta and you will never look at a packet of Parmesan the same way.
