Preserved egg

Also known as Songhua Egg, Change Egg, Easter Egg, Alkaline Egg, Clay Egg. It is an egg food pickled with lime and other raw materials. It is named because of the pine needle-like crystals or patterns in the protein. It is a traditional flavored egg product in my country, which is not only loved by domestic consumers, but also enjoys a high reputation in the international market. When raw duck eggs are marinated in lime and chaff for about 50 to 100 days, they turn into translucent blue-green, which looks much older, so the English name is “a thousand years old”. It has a firm texture, a strong taste and a slightly fishy taste. It is a Chinese delicacy. It is usually cooked after removing the shell and slices and then serving it in the cold.
