Serving & finishing
Method
Make curing mix & prepare eggs
- 1
Sterilize and inspect eggs
Choose 6 uncracked fresh duck or chicken eggs. Rinse gently with warm water and a little dish soap to remove dirt, then rinse thoroughly. Pat dry. If desired, wipe the shells with a little rice vinegar to reduce surface microbes and dry completely.

Prepare alkaline curing powder
In a nonreactive bowl (glass or plastic), combine 1 cup coarse sea salt, 1/4 cup quicklime (or hydrated lime), and 1/2 cup sifted wood ash or powdered tea leaves. Mix thoroughly with a wooden or plastic spoon until uniform. This is the dry curing mix that will coat the eggs.

Prepare alkaline liquid (optional step)
If using alkaline (lye) water rather than only the dry mix, have about 500 ml of lye water or strong soda solution ready. Handle with care: lye solutions are caustic. Wear gloves and eye protection. The liquid will be used to moisten the dry mix when creating a paste or to soak eggs briefly to increase penetration; either method speeds curing but is optional for traditional dry packing.

Coat eggs with dry mix or paste
Option A (dry pack): Pour a layer (about 1/2 inch) of rice husks or clean dry sand into the bottom of a clean, nonreactive container (ceramic crock or plastic bucket). Place eggs on top spaced so they don't touch. Mound the dry curing mix over each egg until fully covered. Add another thin layer of rice husks/sand to fill gaps and support the eggs. Option B (paste): If you prefer a faster, more uniform cure, gradually mix some of the lye water into the dry curing mix until it forms a thick paste (like damp sand). Wearing gloves, roll each egg in the paste until evenly coated, then place coated eggs in a container with rice husks/sand to separate and support.

Seal and store for curing
Cover the container with a lid (not necessarily airtight) or plastic wrap. Store in a cool, dark place at stable temperature between 10–20°C (50–68°F). Cure for 3 to 6 weeks depending on desired intensity: typical 4 weeks yields a characteristic dark translucent jelly and savory flavor. For a more pronounced alkaline effect, cure up to 6 weeks. Check after 3 weeks by cracking one egg to test texture if uncertain.

Duration note and safety
The alkaline curing transforms the egg yolk into a creamy, complex-flavored mass and the white into a dark amber, jelly-like substance. Use fresh, uncracked eggs and maintain clean tools and container to reduce contamination risk. If you used quicklime, ensure you follow safe handling and fully wash off the curing mix during cleaning after curing.
Unpack, clean and finish

Remove, wash and peel
After the chosen curing time, remove one egg and rinse under cool running water to remove the curing coating. Use a sponge or brush to gently scrub away residual paste or powder. Carefully crack the shell and peel. The outer shell may be mottled; beneath, the white will be amber to dark brown and translucent, the yolk a grey-green to olive color with creamy texture.

Slice and serve
Slice each peeled egg into halves or quarters. Arrange on a plate. Sprinkle each portion lightly with 1/2 tsp coarse sea salt (or to taste), drizzle about 1 tbs light soy sauce and 1/2 tsp sesame oil over the slices. Garnish with chopped cilantro or scallion if desired. Thousand-year-old eggs are commonly served as an appetizer or with congee.

Storage of finished pidan
Once peeled and served, unused portions should be refrigerated in an airtight container and consumed within 4–5 days. Unpeeled, cured eggs stored in their curing medium or dry will keep for several months in cool conditions; however, flavor may intensify.
