Beondegi (Korean steamed silkworm larva) is surprisingly OK.
I will literally eat any seafood you put in front of me as long as it's guaranteed not gonna kill me. Baby octopi are delicious.
I challenge you to try hongeo! Korean stingray. It's a holdover from the days of no refrigeration or preservation techniques. Fishermen long ago noticed that hey, it tastes fucking terrible, but it never goes bad and you can eat it and not starve! It never goes bad because it's drenched in ammonia. You ever smell horse urine? That's ammonia. Stingray is the most absolutely vile thing I have ever put in my mouth. I ate one tiny piece and very nearly threw up and have not touched it since.
