Speaking of this oily egg, I have the most say. My mother is the best oily egg I have ever eaten.

1, if you want the color of the egg to look good, you should first look for the bark of the spring bud tree. The soaked eggs are red and look good.

2. Boil the bark of spring buds with water. The water must be boiled, and the right amount of salt should be added.

The key step is to cool the water to 60-70 degrees, find a clean, transparent and sealed glass bottle, and put the spring bud bark water in it.

4, put the duck eggs in the bottle, remember, be sure to seal the bottle, so as to maintain the taste of the eggs.

5. Put the eggs in 15-20 days, take them out and cook them in water, and the oily eggs can be eaten.
