Mould in water when making preserved duck eggs

Mould in water when making preserved duck eggs - Siblings Doing DIY Easter Eggs

We have ducks at home and my wife has been making the Chinese delicacy 咸鸭蛋 preserved duck eggs for about 3 months now.

However in the past week the current batch of eggs has mould in the water.

The weather here is getting warmer as we have just switched to Spring. So we are guessing it might be the extra sunlight or warmth coming into our kitchen.

My wife didn't think we need to put it in the fridge, but is there a suggested temperature?



Best Answer

When my mom made salted eggs, we always put it in the fridge.

How can you tell if a salted duck egg is bad?

How to judge whether the salted egg is good or rotten:
  • First, crack the egg into a bowl.
  • Notice the color of the yolk. It should be bright orange-red and the white should be thick, clear and translucent.
  • Smell the egg. If it smells unpleasant, means the egg is rotten.


  • What happens when duck eggs sink in water?

    If the egg sinks to the bottom of the container in the water, it may not be alive. This is a sign that the egg has a yolk, not a developed embryo. Check if the egg floats at an angle.

    How can you tell duck eggs are bad?

    If it floats, it is rotten. Simple! You should store the eggs broad end up pointy end down, in a cool place.

    Just drop them in a bowl of water and, if they float, they've gone off. But if they sink straight to the bottom, crack those bad boys (eggs) open and get mixing!
