I saw that thing on the Food Network and the smell of it made the chefs gag. 
Wikipedia says that tempoyak is a condiment made from fermented durian. It looks like they mash it up, ferment it, and use it in this lumpy, not-really-beverage like state.
Is it locally available? I don't think I've ever seen one at the grocery stores I frequent, but I can pronounce the names of these grocery stores, so that's probably the first problem.
I think I'll let you be the guinea pig on this one.
