I can't believe you didn't mention Canna Sutra, the chocolate bar that was marketed as an aphrodisiac and had literal Egyptian hieroglyphic-style porn on it. The sample was tasty. The full bar was in a tin, which the vendor took mischievous delight in revealing to interested people.

One nice thing is that several vendors support free or direct trade and were conscientious regarding the farmers and their communities. In addition to taste, I made my single purchase based on this.

I'm not a big buyer of fancy chocolate, so this festival exposed me to a lot of brands and flavors with which I was unfamiliar or inexperienced.
