@MP20895 That sounds like a doujin I saw once.

@Monochrome_Scholar Its fairly widespread, most of the coastal East Asian countries have the practice. Russians pickle that shit, and Sicilians use it as pasta topping. Tbf its really not any more gross than eating fish eggs/roe but we just culturally think one is worse than the other.
@Monochrome_Scholar that was in NZ. It turns out I read that piece of article years ago. Dunno if people there still practice that shit.
