Recipe contributed to the Scharffen Berger book Essence of Chocolate: Recipes for Baking and Cooking with Fine Chocolate by Alice Medrich. From the book: Since we began Scharffen Berger Chocolate Maker, Cocolat founder Alice Medrich has been a constant help, ready to lend a hand with everything from bean tasting to recipe tasting. We’re especially honored to have Alice’s chocolate recipes in our book because both of us are fans of her chocolate confections, which she first began selling in Berkeley in the 1970s. These chocolates have a thin dark shell around a decadently soft center, underscored with the warmth and fragrance of a single-malt Scotch. Alice recommends that you mix this ganache gently with a spatula rather than vigorously with a whisk. Because the chocolate coating is not tempered, the hearts must be stored in the refrigerator to keep them from discoloring or blooming. Enjoy them cold, right from the refrigerator, or let them sit at room temperature for a half an hour or so, to bring up the flavors of the chocolate and the Scotch.
