text: INSTANT ESPRESSO POWDER: Coffee compliments the flavor of chocolate. Instant espresso powder can be found in Italian delicatessens and many supermarkets.  The most common brand is Medaglia d'Oro. It's a little hard to find, but I found a reliable mail order source. However, brands from major American companies are coming onto the market in reaction to the newfound love for "real" coffee.  If you wish, you can substitute regular instant coffee, but it isn't nearly as intensely flavored.
