What is a preserved duck egg?

A preserved duck egg, also known as century egg, is a Chinese preservation process that involves steeping a whole, raw duck egg in a saline solution for several weeks to months. This process turns the egg white into a dark-colored, jelly-like substance and the egg yolk into a creamy, greenish-gray color.
