Jesus I lived with a Korean guy for a bit in halls at uni, he used to smash back seaweed. These thin salty as **** sheets of it, he'd put rice in the middle and roll it up like some fat blunt and stuff the thing down his throat. I tried it once and it was disgusting, another thing that can stay in the sea
My Grandad used to always cook it when I was a kid so it's something I've always had but if I was an adult and hadn't tried it then I'd be thinking it's a wind up.
