I realize the above image could make some people feel physically sick, but I've personally acquired both these most difficult of tastes, and I'm licking my lips at the prospect of a collaboration.
You'll probably know about Guinness, but for those of you who aren't familiar with Marmite, it's a nutritious, vegan-friendly, British foodstuff originally made from the yeast left over by the beer-brewing process. Usually, it's spread thinly on toast, and for those who like it, it has a salty, almost meaty flavor. For those who don't, the flavor is more akin to that of earwax.
In time for St. Patrick's Day, Guinness yeast extract will be used to make a special spread, limited to 300,000 jars. It's available today 19 February 2007 for around Â£2.49 from supermarkets in the UK.
