How long can century eggs 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 have suggested people have eaten unrefrigerated century eggs stored in a pantry for half a year with no ill effects.  Edit: It tasted great. 
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.
