Century egg

description Century egg Overview

Century egg, also known as pidan, is a traditional Chinese preserved food made by curing duck, chicken, or quail eggs in a mixture of clay, ash, salt, quicklime, and rice hulls. This alkaline preservation process, which lasts for several weeks or months, transforms the egg white into a dark brown or black translucent jelly and turns the yolk into a creamy, grey-green substance. It is commonly consumed as a cold appetizer, often dressed with ginger, soy sauce, or sesame oil, and is known for its distinct, pungent aroma and umami flavor.
