Quail Pidan (also known as Century Egg). Quail eggs that have been coated in quick lime and ash and other stuff and left to ferment for a month or two. Sounds gross? It is.
I'm scottish, so some people say my beloved haggis is weird. But most of the people that say this have never had it! mmmm
I've also had calf fries (the testicles from a bull being turned into a steer then deep fried). I almost threw up when I found out what they were. Rattlesnake, buffalo (makes a divine pizza), and guinea pig (really tough!)
