What Is a Century Egg?
A century egg, also known as a preserved egg, pidan, or thousand-year egg, is a traditional Chinese delicacy made by preserving duck, chicken, or quail eggs for several weeks or months.
Despite its dramatic nickname, a century egg is not literally hundreds or thousands of years old. The preservation process usually takes anywhere from three weeks to several months, depending on the production method.
During preservation, the egg undergoes a fascinating chemical transformation:
The egg white turns into a translucent, dark brown or black jelly.
The yolk becomes creamy, soft, and ranges from dark green to gray.
The flavor becomes richer, more complex, and deeply savory.
The result is an entirely different eating experience compared to a regular boiled egg.
Rather than being rotten, the egg is intentionally transformed through controlled preservation, creating one of the world's most iconic traditional foods.
Where Did Century Eggs Come From?
Century eggs have been enjoyed in China for hundreds of years, dating back to the Ming Dynasty.
According to one popular story, a farmer discovered duck eggs preserved naturally in alkaline mud near a construction site. After tasting them, he found that they had developed an incredibly rich flavor rather than spoiling. This accidental discovery eventually evolved into the preservation method used today.
Over time, century eggs became a staple in Chinese cuisine and spread throughout many regions in Asia, where each area developed its own serving style and recipes.
Today, century eggs are considered a classic ingredient in Cantonese cuisine and are often served:
As a cold Chinese appetizer
With pickled ginger
In congee
With tofu
Alongside other delicacies in traditional banquets
Why Is It Called a Century Egg?
This is probably the biggest misconception surrounding the dish. The name "century egg" is simply a colorful nickname. The eggs are not aged for 100 years.
They're also not 1,000 years old, despite another common name: thousand-year egg.
The dramatic names originated because the eggs look incredibly old after preservation, with their dark colors and unusual textures. Early Western visitors translated the names literally, and the myth has remained ever since.
In reality, most commercially produced century eggs are preserved for only a few weeks to several months.
Is Century Egg Safe to Eat?
One of the most common questions people ask is: Is century egg safe to eat? The answer is yes when it is properly produced and purchased from reputable sources.
Century eggs are preserved through a controlled chemical process, not by allowing the egg to rot. The alkaline environment actually prevents harmful bacterial growth during preservation.
Modern commercial production follows food safety standards, making century eggs perfectly safe to enjoy.
Common Myths About Century Eggs
Because of their unusual appearance, century eggs have become the subject of many internet myths.
Myth 1: They're hundreds of years old.
False. Most century eggs are preserved for only a few weeks or months.
Myth 2: They're rotten eggs.
False. Rotten eggs spoil due to bacterial decomposition. Century eggs are intentionally preserved through an alkaline curing process, which transforms the egg instead of letting it decay.
Myth 3: They're unsafe.
False. Properly produced century eggs are safe to eat and widely enjoyed throughout Asia and around the world.
Myth 4: They smell terrible.
Not exactly. Century eggs do have a stronger aroma than regular eggs, but it isn't a sign that they've gone bad.
Many people compare the scent to strong cheese, but enjoyable once you become familiar with it.
What Does Century Egg Taste Like?
Surprisingly, century eggs are much milder than they look. The flavor is often described as:
Rich and savory
Deeply umami
Creamy
Slightly earthy
Mildly mineral
Smooth with a lingering finish
The yolk is especially luxurious, almost resembling a rich cheese or creamy custard in texture.
Meanwhile, the translucent egg white is firmer and slightly bouncy, offering an interesting contrast.
The unique flavor becomes even more enjoyable when paired with ingredients that add freshness, acidity, or crunch.
That's why century eggs are often served with ginger, vinegar, tofu, or refreshing appetizers.
