This chocolate comes from an Italian chocolatier, though I can't find much information about it; I found this bar and others of theirs on sale at Whole Foods. The ingredient listing is good, cocoa mass, sugar, cocoa butter, soya lecithin and chili pepper oil (2%). The cacao content is at 53%.
How does it taste? I've had other peperoncino bars, essentially chili pepper and chocolate, a good combination normally; this one is deceptive, in that when you first eat it, you don't get the heat, you get it in the aftertaste. Even so, it's not too hot. The chocolate itself is good but not great, overall a pleasant eating bar. This bar cost me $4; normally $5.
