How to choose high-quality salted duck eggs?
1, look at the surface
Good quality salted duck eggs are smooth and clean, without any spots and cracks, and the eggshells are blue-gray. If the shell is black and white and there are many spots, it means the quality is not good.
Step 2 shake the egg
Shake the salted duck eggs when you choose them. Because good quality salted duck eggs will hear the sound of oil flowing in them when they are shaking, but poor quality salted duck eggs do not have this sound when they are shaking, so they should be shaken vigorously when choosing salted duck eggs.
3. Light
Hold the duck egg gently and watch it in the light. Good duck egg protein is clear and transparent, and the empty room at one end is relatively small. If it is a duck egg of poor quality, the empty room is relatively large and gloomy.
