I also discovered a trick when making pickled beets, I put in some hard boiled eggs, which normally turn a uniform dark red and are delicious. But this time, one of them I put in "tea egg style", somewhat cracking the shell but leaving it on.
Imagine eggs that looked like this, but with red, instead of brown, 'veins':

Is that balut eggs?
