It's one of the things I grew up to like. I didn't like it as a kid (in fairness, past a certain age, my old man's congee ceased to be appealing), so when I started making my own (chicken liver congee is great, but finding chicken liver is a bit of a pain), and after moving, I make my own hundred year egg and minced pork congee. Easy, quick, and pretty damn tasty. The missus also introduced me to a shockingly simple oyster sauce, tofu and hundred year egg combo which is weirdly good.I'll never understand why people actually throw up or gag when they eat century eggs. I fucking love the things, ever since I was a child.
It's one of those stereotypical things and when people are goaded into eating it it's by itself and with the main focus being the yolk, which has a really sulphurous odour which is where the hate is generally directed. Actually cook the stuff in something and it's not just palatable.
