I'll have to tell my tale of an accidental encounter with Pepper Pot Soup... But thinking of it makes me heave. I think it's popular with French Canadians. I'd never seen it back home, but now I'm close enough to Ontario that it is in the stores. Somehow I managed to grow up in a state with tons of Mexican food and not ever taste menudo, so this was my first, and last, encounter with tripe.
CP, save yourself. Don't seek out Vegemite. LOL
HWA, your comment reminded me of a funny comment when I googled it, about Americans slathering it on an inch thick.... Probably because we do that with peanut butter, which is practically a staple food. I heard another funny thing - that Vegemite is proof that you can train people to eat anything if you start young enough.
