Rich, intensely-flavored dessert from Fine Cooking. I made this especially for my husband, whose #1 drink of choice is espresso. You'll definitely want to use top-quality chocolate and, of course, good, fresh coffee beans. I used 8 ounces of bittersweet chocolate, rather than the semisweet/unsweetened combination, and refrigerated overnight before serving. The original recipe listed double-strength coffee as an alternative to the brewed espresso, but I would only use this if you have no means to brew espresso, or, at least, access to purchased shots.
