Zombie notwithstanding, why are you cooking it? Or do mean merely warming it up a bit to speed up fermentation? Because once you get in the 50C range, you're killing your yeast. And does Marmite even have live yeast cultures? I would imagine with all the salt and heat processing, it'd be dead, and any fermentation you happen to get is just happenstance.
