2 ounces brewed espresso, room temperature or chilled (not hot)
Softly whipped cream, for garnish
Bittersweet chocolate, for garnish
Put the liquors and espresso in a chilled cocktail shaker. Shake well until very cold, then strain into 2 chilled martini glasses. Float a layer of whipped cream over the top. Using a vegetable peeler, shave some dark chocolate on top of each glass.
