Eight-inch preserved eggs

Wujiang's "eight preserved eggs" has a history of hundreds of years. According to legend, during the Taichang period of the Ming Dynasty, there was a small teahouse in Wujiang, and the business was booming and the guests were very busy, so the owner poured the tea residue into the ashes. His ducks often lay eggs on the ashes, so the owner will inevitably miss the duck eggs. Once, the owner found a lot of duck eggs when cleaning the furnace ash residue, thinking that they could not be eaten. Who knows, when they were peeled open, they were dark and bright, with white pine needles on them, which smelled fragrant and tasted fresh and refreshing. This is the original preserved egg. When making "eight preserved eggs", fresh duck eggs are put into a pre-prepared feed liquid tank, and the feed liquid formula consists of a certain amount of soda ash, quicklime, inorganic salt and water, etc. After the tank is sealed and soaked for 25-35 days, the duck eggs after being discharged from the tank become edible preserved eggs.
