1, buy fresh duck eggs. Be sure to check whether there is a cracked shell, and discard the cracked shell, otherwise it will be very salty.

2. Carefully rinse off the dirt on the shell one by one with running water.

3. Absorb water with a paper towel or dry it in a ventilated place until it is completely waterless.

4. Pour some high-alcohol liquor into a disposable plastic cup to ensure that the duck eggs can be completely submerged after entering. Every egg does this once.

5. Then gently put the duck eggs soaked in white wine in a big bottle that can be sealed one by one.

6. Put all the prepared marinated spices into water and boil them in cold water. Then pour enough salt until the salt can't be dissolved further (that is, saturated state).

7. After the brine is completely cooled, pour it into the container containing duck eggs at one time to ensure that all duck eggs are immersed in salt water. Finally, add a little white wine, cover and seal the bottle with water.

8. Take it all out after sealing for 20-30 days, and cook it in cold water.
