What is a fermented egg?

Fermented eggs, also known as century eggs or thousand-year-old eggs, are a delicacy in many Asian countries. They are made by preserving raw duck, chicken, or quail eggs in a mixture of clay, ash, salt, quicklime, and rice husks for several weeks to several months. During this time, the eggs undergo a chemical reaction that results in a creamy yolk with a gelatinous texture and a pungent, ammonia-like smell.

Despite their strong flavor and odor, century eggs are considered a delicacy and are enjoyed in a variety of dishes, such as congee, salads, and traditional Chinese mooncakes. They are often served as a side dish or used as a topping in soups and noodle dishes.

Century eggs are an acquired taste and may not be appealing to everyone due to their unique flavor and aroma. However, for those who enjoy them, they provide a rich and savory addition to many dishes.
