Century egg is a type of preserved ingredient in Chinese cuisine. Learn how to eat it with 3 rice porridge recipes and 3 soup recipes.
Born out of an approach not to waste food, whenever there is an egg glut, egg farmers will preserve them so that they don’t spoil. Salted egg is another type of preserved ingredient. Century egg is also called the thousand-year egg but it is not actually that old. It only takes around a month to make.
The Mandarin name is 皮蛋 (pi dan) which roughly means “leather egg”. Why such a bizarre name?
It could be because of its colour. The egg is generally blackish and brownish. The egg white is brownish, like firm jelly, and is tasteless. The texture is similar to a hard-boiled egg. The egg yolk is greyish and creamy. Some say it has a sulphurous smell. I had very little encounter with sulphur, so I can’t say.

Snowflake-like patterns sometimes appear on the egg white. It used to fascinate me when I was a child. The next time you buy century eggs, try looking for these patterns.
Century egg is usually made with duck eggs but chicken eggs have been preserved as well. The preservation ingredients are generally considered toxic. However, in recent years, the making of century egg has become more modern using healthier ingredients. One Taiwan manufacturer even only uses sea salt and sodium bicarbonate.
Bizarre Food
It is interesting to note that century egg is considered a bizarre food in many parts of the world. I was quite amused by the fuss surrounding this very “old” egg. I saw a few YouTube videos of people trying it for the first time. I knew they were going to gag or throw up because most of them took such huge bites which would obviously be overpowering. Would anyone wolf down an entire piece of blue cheese? No, right? You slice a little piece and smear it thinly on a large biscuit, right? The same principle goes for the century egg.
Washing the egg
The eggs we buy locally used to have rice husks and mud still intact. The eggs come individually wrapped in plastic to prevent the mud and husks from falling everywhere. But I have seen shops selling century eggs pre-washed. I don’t quite trust those initially as I was told that the mud and husks protect the eggs.
It does make sense to buy pre-washed eggs as it is quite messy removing the husks and mud. I used to scrap the mud off with a butter knife. But it made a mess in the kitchen sink and I worry that the husks might clog up the drain.
I tried rubbing off the mud and husks with my hands while the eggs are still wrapped in plastic. It is less messy. Loosen the plastic a little and then use the thumbs to push the mud away from the shell. Wash off any leftover mud.
Only remove the shell after it has been thoroughly cleaned.
Slicing the egg
Slicing the century egg can be a challenge too because the yolk is soft and creamy, and tend to stick to the knife.
Smearing oil on the knife helps. Using dental floss or thread is more effective. Place the egg on the chopping board. Hold the dental floss in both hands and press down on the egg. Continue until you have the chunks you want.
Having said that, many people still do not like the taste as it can be quite strong. Alex of Justcookit.blogspot.com wrote a controversial post of his first encounter with it. It is quite funny, if you need a good chuckle, head on over.
I have probably acquired a taste for it because I can eat it on its own with just some preserved ginger. I suggest interested newbies try it in very small pieces and never on its own. Eat it with lots of rice congee. (^__^).
Century Egg Porridge
Century egg goes very well with rice congee. Just watch the video below where a guy tries the century egg together with the congee for the very first time. What is his verdict? “Century egg is terrible unless you have it with congee.“
