Regarding the photo... it might not look like much. I was too lazy to be artsy. But trust me, it tastes great! :D
1/2 pound good bittersweet chocolate
1/2 pound good semisweet chocolate
1 cup heavy cream
2 tablespoons orange-flavoured liqueur (optional)
1 tablespoon prepared coffee
1/2 tablespoon good vanilla extract
Chop the chocolates finely with a sharp knife. Place them in a heat-proof mixing bowl. (Personally, I used a food processor for this)
Heat the cream in a small saucepan until it just boils. Turn off the heat and allow the cream to sit for 20 seconds. Pour the cream in a fine-meshed sieve into the bowl with chocolate. With a wire whisk, slowly stir the cream and chocolates together until chocolate is completely melted. Whisk in the orange-flavoured liqueur, if using, coffee and vanilla. Set aside at room temperature for 1 hour.
With 2 teaspoons, spoon round balls of the chocolate mixture onto a backing sheet lined with parchment paper. Roll each ball of chocolate in your hands to roughly make it round. Roll into cocoa powder.
These will keep refrigerated for weeks but serve them at room temperature.
