Close. Marmite is made from meat extract. Vegemite is made from yeast extract. But Marmite's crap and Vegemite's great!
Marmite is yeast extract as well. (Pretty damn sure it is anyway)
No idea what the hell vegemite is anyway. Probably just a marketing ploy.
I personally can't stand the stuff. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> Unless its on a twiglet for some reason...
