The manufacturing method is as follows:
The traditional method of making preserved eggs is almost always using yellow lead powder (Chinese medicine), also known as Lithuanian monk, that is, lead oxide, so the lead content of preserved eggs is daunting. The following is how to make lead-free preserved eggs.
The raw materials are:
Raw eggs: 100 duck eggs (eggs and quail eggs are also acceptable).
Edible salt: 3 Liang
Quicklime: 3 Liang
Soda soda: 3 Liang
Black tea: a little.
Plant ash: Seven.
Rice husk: appropriate amount (or sorghum husk and grass ash instead)
Clear water: right amount
(1) Stir-fry the salt in the pot, and then take it out and grind it when the explosion stops.
(2) Sprinkle massive lime, chop it into powder, and sieve it for later use.
(3) 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 when operating to prevent strong alkali from harming the skin.
(4) Roll the wrapped eggs back and forth on the rice husk, cover the rice husk and put them in another jar.
⑤ After the cylinder is full, seal it with yellow mud, salt and water.
