Preserved Century Duck Egg with Oyster

The preserved century duck egg, a traditional Chinese ingredient dating to the Ming Dynasty, is created by preserving duck eggs in a mixture of clay, ash, salt, and lime, resulting in a creamy, pungent yolk and a translucent, jelly-like white. When paired with fresh oyster, the dish combines the egg’s rich, earthy depth with the oyster’s briny, sweet umami—a contrast that exemplifies Cantonese coastal cuisine. According to food writer Michael Ligier, a notable version is served at the Hong Kong restaurant **Wing** in Central, where the dish is treated with careful balance. A great rendition hinges on the century egg’s texture: the yolk should be silky and almost molten, not dry or chalky, while the oyster must be plump and freshly shucked, never overcooked. Common accompaniments include thin slices of ginger, a drizzle of soy sauce, and sesame oil to cut the richness. Regionally, century eggs are more often seen in congee or cold tofu salads in northern China, but the oyster pairing is especially popular in Hong Kong and the Pearl River Delta, where both ingredients are abundant. Some variations add a splash of Chinkiang vinegar or chili oil for acidity and heat, but purists favor the unadorned interplay of flavors. The dish may be served as a cold appetizer or a light main course, with the century egg sliced and nestled atop or beside the oyster.
