Ah, yep, that checks out. Korea (and to a similar but lesser extent, Japan) is kinda wild like that. I heard about some stuff like that from my (Korean) ex’s extended family.

Btw - assuming you’re into interesting and tasty food, you should try soy marinated raw crab (Ganjang-gejang / 간장게장) from a good shop - I tried some first time I went to Seoul and fucking LOVED it, and actively sought it out the next time I went lol. Definitely nonstandard and “adventurous” for a western-acclimated palate, but it’s very fucking tasty if you are down for it. It’s definitely way better in Korea at a place that does it very fresh - you can get them jarred in a bunch of Asian groceries (in the US at least), but the taste and texture is not nearly as good, imo.
