never had marmite but if its anything like vegemite i dont wanna try it. no offense, but that stuff is disgusting. i even tried to like it. its impossible. but on the other hand, aussies looked at me like i was a whacko for the pbj. i couldnt believe it when they had never had or even heard of a pbj. to each their own i guess. but you know, vegemite is the worlds richest known source of vitamin b. i think.
