Question: How long can [century eggs](http://en.wikipedia.org/wiki/Century_egg) last for refrigerated and unrefrigerated? I have some slightly cracked eggs from a friend who has stored it for months in his refrigerator.

[A few comments from this blog](http://nookandpantry.blogspot.com/2007/05/century-eggs.html) have suggested people have eaten unrefrigerated century eggs stored in a pantry for half a year with no ill effects.

Edit: It tasted great.

Answer: 
Century eggs are a preserved food. Unopened, they can last for a very long time, possibly years, without refrigeration. They are sold at my "local" Asian supermarket in the dry stock aisles. Once opened you can keep them in the refrigerator for a few days. Or make chok or congee and have the left overs for breakfast.
My friend in Taiwan says they will keep refrigerated for up to 5 months - possibly longer but why risk it?
