Plant ash and Gao Liquor can be used for salted eggs, but it is the salt that makes the eggs salty, and plant ash is only the carrier that makes the salt fully contact with the eggs. In other words, without salt, only plant ash can't make eggs. However, high-alcohol liquor is beneficial to sterilization and salted egg oil production. When pickling eggs, add salt according to the ratio of one or two salts per catty of eggs. Boil the salt with cold boiled water, add a small amount of high-alcohol liquor and mix well with plant ash. Plant ash's quantity is limited to wrapped eggs. The wrapped eggs should be put in a sealed container and kept in a cool place, and they can be cured in about 20 days.
