Hello everyone, I am Da Lei, duck eggs also known as duck spring, green skin, etc., rich in protein, fat and a variety of trace elements, but also often used in our lives of the delicacies.
I remember when I was a child, my grandmother fed several ducks, pickled a large jar of salted duck eggs, every time I came back from school, I could almost eat boiled duck eggs, time flies, decades rushed by, and now even if the living conditions are good, I can no longer eat the duck eggs cooked by my grandmother.
When you want to eat, you can only go to the market or supermarket to turn around, but find that there are two colors of duck eggs, one shell is white, one shell is cyan, so which one should be bought?
