As an horsвЂ…d'Е“uvre, the Cantonese wrap chunks of this egg with slices of pickled gingerвЂ…root (sometimes sold on a stick as streetвЂ…food). Although zinc is essential for life, excessive zinc consumption can lead to copperвЂ…deficiency, and the finished product should have its zinc level assessed for safety.Д¬entury eggs can be eaten without further preparation other than peeling and rinsing themВ вЂ“ on their own, or as a side dish. The extremely toxic compound lead(II)вЂ…oxide speeds up the reactions which create century eggs, leading to its use by some unscrupulous producers, whereas zincвЂ…oxide is now the recommended alternative. This is because the chemical reaction needed to produce century eggs is accomplished by introducing hydroxide and sodium ions into the egg, regardless of the method used. Today, soaking raw eggs in a solution of tableвЂ…salt, calciumвЂ…hydroxide and sodiumвЂ…carbonate for 10 days, followed by several weeks of aging while wrapped in plastic, is said to achieve the same effect as the traditional method. ModernД®ven though the traditional method is still widely practiced, modern understanding of the chemistry behind the formation of century eggs has led to many simplifications in the recipe. The mud slowly dries and hardens into a crust over several months. It is then rolled in a mass of rice chaff, to keep the eggs from adhering to one another, before the eggs are placed in cloth-covered jars or tightly woven baskets.

Each egg is individually covered by hand, with gloves worn to protect the skin from chemicalвЂ…burns. To the tea, 1.4В kg (3В lb) of calciumвЂ…oxide (3.2В kg or 7В lb, if done in winter), 4.1В kg (9В lb) of seaвЂ…salt, and 3.2В kg (7В lb) of ash from burned oak is mixed into a smooth paste. A recipe for creating century eggs starts with the infusion of 1.4В kg (3В lb) of tea in boiling water. The addition of calcium oxide and wood ash to the mixture lowers the risk of spoilage and also increases the speed of the process. Instead of using just clay, a mixture of woodвЂ…ash, calciumвЂ…oxide, and salt is included in the plastering mixture, thereby increasing its pH and sodium content. The traditional method for producing century eggs developed through improvement of the aforementioned primitive process. In her honour, the farmer named the transformed eggs with their delicate crystalline patterns on their surfaces 'pine-patterned eggs'. The eggs were not discovered until the woman cleaned out the ash pit half a month later where they had turned into century eggs. water-brother), also from Hunan, leaving duck eggs in the garden of a woman by the name of Songmei (жќѕе¦№, lit. An alternate story involves a young duck farmer by the name of Shuige (ж°ґе“Ґ, lit. Upon tasting the eggs, he set out to produce moreВ вЂ“ this time with the addition of salt to improve their flavorВ вЂ“ resulting in the present recipe of the century egg. Its discovery, though not verifiable, was said to have occurred around 600 years ago in Hunan during the MingвЂ…Dynasty, when a homeowner discovered duck eggs in a shallow pool of slakedвЂ…lime that was used for mortar during construction of his home two months before. The century egg has at least four centuries of history behind its production. The clay hardens around the egg and results in the curing and creation of century eggs instead of spoiled eggs. The method for creating century eggs likely came about through the need to preserve eggs in times of plenty by coating them in alkaline clay, which is similar to methods of egg preservation in some Western cultures. In 2014, 3 million tons of Songhua eggs were consumed in China. These patterned eggs are regarded as having better quality than the normal century eggs and are called Songhua eggs, also known as pine flower eggs or pine-patterned eggs ( Chinese: жќѕиЉ±и›‹). Some eggs have patterns near the surface of the egg white which are likened to pine branches. This chemical process breaks down some of the complex, flavorless proteins and fats, which produces a variety of smaller flavorful compounds. The transforming agent in the century egg is an alkaline salt, which gradually raises the pH of the egg to around 9вЂ“12, during the curing process. Through the process, the yolk becomes a dark green to grey color, with a creamy consistency and strong flavor due to the hydrogenвЂ…sulfide and ammonia present, while the white becomes a dark brown, translucent jelly with a salty flavor. Century eggs ( Chinese: зљ®и›‹ pinyin: pГdГ n Jyutping: pei4 daan2), also known as preserved eggs, hundred-year eggs, thousand-year eggs, thousand-year-old eggs, millennium eggs, skin eggs, or black eggs, are a Chinese egg-based culinary dish made by preserving duck, chicken or quailвЂ…eggs in a mixture of clay, ash, salt, quicklime, and riceвЂ…hulls for several weeks to several months, depending on the method of processing.
