What’s a century egg

Century eggs have a large group of other names: Chinese preserved eggs, Chinese black eggs (because some century eggs are black ), or even 1000-year-old eggs.

In fact, there are two popular types of preserved eggs in China including salted egg and this century egg. The Chinese name is “皮蛋”. “皮” actually refers to the extra shell of the egg. So you can understand the Chinese name “皮蛋” as “Coated eggs”. Its pronunciation is Peedan eggs in Mandarin Chinese.

On the surface of the century egg, there are beautiful crystallizations of amino acid salt, similar to pine flowers, on the surface of the eggs. So those eggs are also called pine flower eggs.

What does a century of eggs taste like

In terms of taste, the white part and the yolk part are quite different from each other.

What does century egg yolk taste like

The creamy yolk is considered the star of a properly century egg. Its texture transforms from liquidy and runny before curing to a rich, thick custard-like consistency with the following features:

  1. You will find the century egg yolk to be super smooth and creamy, custard-like texture when you bite it. When you cut a century egg with knives, it may stick on the palate.
  2. Century egg yolk is much softer than standard egg yolk with a rich and indulgent mouthfeel. It tastes like creamy custard with a leading sweetness and earthy notes.
  3. You can also feel strong umami savoriness along with the creamy, custard-like texture.

What does century egg white taste like

In contrast to the opulent yolk, the egg white transforms into a grey-black or golden-yellow translucent jelly-like solid with a bouncy texture. The taste of the egg white can form a lovely comparison with the creamy egg yolk.

Century egg white is firm, with a jelly-like texture, similar to a jelly dessert made with gelatine. You can find it is super easy to cut compared with the egg yolk.

It has a strong savory umami taste with subtle smokiness. There is no sweetness that can be found in the yolk white, instead, you may find a feeling of minerals.

Although I tried my best to describe the taste, you may still find the taste of century egg is quite hard to imaging. I would love to describe the century egg like a gelatine jelly wrapping a custard creaming filling. Well, I still recommend you try one bite at least to explore the treasure from Eastern.

Chinese people share health concerns about century eggs too. The first problem is heavy metals especially lead. Heavy metals are used to seep up the solidifying process of the protein in the traditional method. But the process has been modified a lot and modernized production uses EDTA as a substitute for lead oxide. So century eggs from the good channel have very little lead.

  1. I purchased a package of 6 Peedan Eggs/Preserved Duck Eggs. They were in a refrigerator when purchased from the Asian store. Do they have to remain under refrigeration until eaten or can they be stored (unopened) at room temperature? Secondly, what is the ‘use by’ or ‘expiration’ date? There is nothing anywhere on the package about storage or expiration dates. I emailed the manufacture several months ago, but have yet to receive a response. Can you help me with this? We don’t want to try to eat the eggs if they are not preserved, but rather – spoiled.

    1. Hi Lorraine,
      Century eggs can be kept in room temperature. Use by means the expiration date. You should use the eggs before that date on the bottle.
