The Mysterious Transformation of Salted Eggs

Duck eggs undergo a radical change when cured in salt, turning their yolks into firm, bright orange-red spheres. This process transforms the egg whites into a jelly-like texture with a deep, savory aroma.

To create these delicacies, producers soak duck eggs in brine or pack them in salted charcoal for weeks. The curing process draws out moisture, which gives the yolk its unique, rich texture. These eggs are often used as a prized ingredient in mooncakes and traditional rice dishes. Many people are surprised to learn that a simple salted pack can fundamentally change an egg's chemistry.
