Black, white and seemingly bland pidan tofu isn't a likely candidate for "love at first bite" fame. But after a few tries it becomes a minor addiction for many eaters.
Pidan, or century egg, is a duck egg preserved in clay with seasonings. With time, the egg white turns into a translucent black jelly and the yolk develops a unique flavor. It's topped with sesame oil, vinegar, soy sauce, coriander, chopped spring onion and, sometimes, pork floss. Mash it up and it's ready to eat.
