We usually eat them fried, boiled, or as an accompaniment to other dishes. In different parts of the world, eggs are prepared in highly original ways.
For example, in Chinese culture, a delicacy called century egg, black egg, or skin egg has been around for centuries. The egg, usually a duck egg, is fermented for several weeks in a mixture of lime, rice straw, and tea infusion. The name “century egg” comes from the fact that their connoisseurs, like wine connoisseurs, recognize that the older, the better. These eggs are also used in Chinese medicine as a diet for the sick. In that case, their preparation takes less time, and they are dropped into salt water mixed with clay and soot.
