Hmm… It’s hard to pick the most exotic food I’ve eaten, but here are some things I’ve tried:
Sundae - Korean Blood Sausage (also ate in a stew)
Dalkbal - Chicken feet
Jokbal -pig’s feet
꼼장어구이 - I struggle to romanise this. It’s a kind of grilled eel, but it’s the only eel I’ve eaten and not liked lol.
Ganjang gejang - Marinated raw crab? Soooo good, honestly, my favourite thing on this list.
Black pudding (also blood sausage)
Dutch pickled herring
And when I was a kid, my parent made me try crocodile and bison.
For reference, I live in Europe but have previously lived in South Korea.
