A year or two ago, I was at a convention. In the open convention suite, someone had put out a giant bag of something I only remember being called Montezuma hot chocolate mix - a bag of dry mix to add to hot water made of cocoa, chili, cinnamon, and various herbs (pieces of leaf, this was not all powder) meant to imitate the original chocolate drink of the Aztecs. I took a flier that told about it and where to order it (and that they had a version that wasn't so spicy - literally, it was so spicy I couldn't drink very much)... and of course I've since lost the flier. Googling for various related terms hasn't turned up anything. Any ideas?
