Hahaha... It's an amazing Mexican dish... very famous and very popular within Mexico, but it seems to be almost unknown without Mexico. The most popular is mole poblano - "the concoction from Puelba". It's made with about 10 or 20 ingredients, bread, tortilla, nuts, seeds, fruit, chile and chocolate. So it has this mix of flavours: sweet, spicy, bitter. If you're ever in Mexico, or see it on a menu, I highly recommend trying it. I think I'll go get some now.
