It was originally called "horumon nabe," from horu mon — literally "the things you throw away" — because it was built entirely from beef and pork offal cuts butchers couldn't otherwise sell.
Beef or pork offal is simmered at the table in a shallow pot with a wall of garlic chives, cabbage and a soy or miso broth, traditionally finished by tipping in noodles or rice to soak up what's left once the meat is gone.
