Hmm that's hard to say. Not the salmon roe. I don't think sea urchant is too weird but I didn't like it. Kim chee? Nope. Sheep's milk yogurt? Naa... This is hard... I guess I'll go with the espresso crusted cheese.
It's a delicacy in China. They're duck eggs preserved in the ground for no more than 100 days [despite the absurd title they already have]. Honestly, they tasted really good, but... They look so unappetizing.
