A quick sketch of a Chinese way of preserving eggs, the first time I've actually bought them!

This is one way I can live without but, makes a good drawing subject, although impossible to get the jelly-like consistency of the pi dan. The other black duck egg I thought would be the same but was extremely runny. (and much stronger egg smell than the other)
Scrambled, fried, omelettes and chocolate to follow.
