Century egg or pidan (Chinese: 皮蛋; pinyin: pídàn), also known as preserved egg, hundred-year egg, thousand-year egg, thousand-year-old egg, and millennium egg, is a Chinese cuisine ingredient made by preserving duck, chicken or quail eggs in a mixture of clay, ash, salt, lime, and rice hulls for several weeks to several months, depending on the method of processing.
Through the process, the yolk becomes a dark green to grey colour, with a creamy consistency and an odor of sulphur and ammonia, while the white becomes a dark brown, translucent jelly with little flavor. The transforming agent in the century egg is its alkaline material, which gradually raises the pH of the egg to around 9, 12, or more during the curing process.[1] This chemical process breaks down some of the complex, flavorless proteins and fats, which produces a variety of smaller flavorful compounds.
Some eggs have patterns near the surface of the egg white that are likened to pine branches, and that gives rise to one of its Chinese names, the pine-patterned egg.





I wan to bring my meleis frend go eat pei tan chikin bubur + salted vege 
but halal or not ?

You have to wonder at the curiosity of ancient people finding the technique and the will to eat a black egg for the first time.

i think during ancient time there's no fridge or vacuum air tight plastic bags, chemical etc to preserve food.
that's why ppl resort to preserve food (in this case duck eggs) with clay+salt+lime et al the natural stuff, hence created "century eggs"

i have seen malays eating this egg, if not mistaken they call it "telur pindang". should be no problem. but the shop halal or not?

don't think.
your imagination is irrelevant.
you think too much.

It all happened like this

in long long ago times,
chinese of the teochew clan used to rear ducks at their backyard
which happens to be their open toilet too.

them were amazed some eggs collected tasted somewhat different
not good, but pungent and somewhat still edible.

later they found out those eggs were accidentally soaked in their urine

they eat those good eggs and sold those urine eggs to the market as medicine eggs.
surprisingly, the marketing plan worked.

thereafter they purposely soak those eggs in urine

i quite certain you are speaking in front of your reflection
