things I have not tried are: haggis (where would I even get this I live in Australia and previously in SEAsia) crickets, chitlins (what is this), pigs ears (knowingly - I might've tried em in soups and things IDK), squirrel, rattlesnake, brains, chicken feet (i know, it's mainly coz I have a squick about feet. I have had frogs legs tho)
no idea what razor clams are? I don't THINK I have had blood sausage, unless there was some on the sample plate in Hanhdorf that one time but IDK, and I cannot actually say if I've had real century egg or not. I mightve. But IDK
also oxtail soup is pretty much standard... what is weird in that
