No, other raw materials are needed.
Every family's formula is different, but it is not only the raw material of quicklime.
Method of making lead-free preserved eggs 1:
Raw materials:
Duck eggs (eggs and quail eggs can also be used) 100, 3 liang of salt, 3 liang of quicklime, 3 liang of soda, a little black tea, 7 portions of plant ash, appropriate amount of rice husk (or sorghum husk and plant ash instead) and appropriate amount of clear water.
Exercise:
Stir-fry the salt in the pot, take it out and grind it after the explosion stops.
Sprinkle with massive lime, break it into powder and sieve it for later use.
Boil water, black tea and salt in a pot, then pour them into a jar with quicklime, soda ash and plant ash, stir them evenly to make them paste, and then wrap the eggs with them. It should be noted that gloves must be worn during operation to prevent strong alkali from damaging the skin.
The wrapped eggs roll back and forth on the rice husk, cover the rice husk and put it in another jar.
When the cylinder is full, seal it with yellow mud, salt and water.
Tip:
Generally, it takes 25 days in spring and autumn, 20 days in summer and 30 days in winter to become preserved eggs. This method is simple and easy to use, no matter how many eggs are used, it is very suitable for family use.
Raw materials: raw eggs or duck eggs, salt, tea and its alkaline substances (such as lime powder, plant ash, dilute hydrochloric acid, sodium hydroxide solution, etc. ).
Practice 2:
1. Wash the duck eggs bought from the sales market and prepare a vessel in advance, preferably a porcelain jar. First of all, put the prepared ammonium bicarbonate and edible salt into a container, pour boiling water, and put them in after the quicklime powder and firewood ash are fully dissolved. When all the quicklime powder melts, the ash is ready.
2. Spread the ash prepared in the first step evenly on the shell of duck eggs, then put it in a vessel and put it in a cool and naturally ventilated place for about two months, and the preserved eggs will be preserved.
