First thing that pops up/come into my mind is Pidan/
Preserved Egg, it is also known as the 'Thousand
Year-Old Egg.
This dish is usually served as appetizer or
cooked in A porridge with pork. The eggs are
pickled and fermented in an anaerobic
container for 20 days. During this process,
the proteins in the egg yolk will break down
into amino acids and release ammonia.
Therefore, the ammonia flavor in the
Thousand year-old egg brings the egg itself a
dainty and mysterious flavor.
Besides, there are two extreme comments about
Pidan, one is absolutely tasty/delicious and
the other is unpalatable…it depends.
Thx!
