I have tried several chocolate bars that combine chocolate with chili flavor of one sort or another, and this one is by far my favorite. No great surprise, really, given the amazing nature of all Theo chocolate bars.
I didn't want my impressions to be guided, so I tried my first bite without having read the label. (Beyond seeing the chili pepper on the front and thinking, "MINE.") I was surprised at the complexity of the flavor. The bars I have tried before have been very one-note flavors: you got your "chocolate," and you got your "spicy heat," and that is about it. But in this bar, the spice fades in and out depending on the bite. And at least once, I got a pretty good little kick from an extra-hot bit of chili.
