i had a mate years ago who worked at ICI in warrington. i think he was in some sort of R&D lab.anyway his place had developed a new substance and he offered me a taste, saying it was a new kind of marmite.
well i'm one of the multitude who can't stand marmite, but i didn't want to refuse my friend and also thought the new stuff might be an improvement.
well it was as nauseating as the original, and i gagged even more when he told me it was made from a compound of petroleum by products and recycled plastic!!
ugh!
