Casu marzu 意大利卡苏马苏活蛆奶酪
How do you improve a nice sheep-milk pecorino? In Sardinia, you start by cracking open the cheese and letting a whole lot of flies settle in. As they eat, poop and lay their eggs in the cheese, the flies impart unique flavors that are only improved by the texture of the wriggling maggots after they hatch. Yes, you're supposed to eat them, too.
Century egg 松花蛋
Enjoyed in China for hundreds of years, the century egg is a duck, chicken or quail egg steeped for up to five months in a special broth that includes black tea, salt, lime and wood ash.
