Chinese chefs are not afraid to experiment with tastes and flavors, and they invented an extremely unusual and dangerous dish called "century eggs." Traditionally, this delicacy was made by preserving chicken or duck eggs in a mixture of salt, lime, and ash for 100 days. Once this process is complete, the dish is ready to serve. The century eggs have a translucent, jelly-like texture with a strong stench of ammonia. You’ll need a strong stomach to handle this one.
