I'm not sure how to describe what I've recently tasted from Minneapolis' Rogue Chocolatier. I'm not used to eating chocolate that's as complex as fine wine or beer, as satisfying as a cheese plate, or as rich as King Midas. I know that I'm prone to superlatives, but here I go again: Rogue Chocolatier's Sambirano (the only kind I've tried so far), single-origin chocolate from the Sambirano Valley in Madagascar, is as good as any chocolate I've ever had.
