1. In microwave using medium-low power, melt chocolate in a medium-sized bowl-- the length of time this will take will depend on the strength of your microwave, but expect it to take at least 1 minute. 2. Whisk in butter and egg yolk until blended; then whisk in liqueur and icing sugar until smooth. 3. Cover and refrigerate until firm enough to shape, about 1 hour. 4. Shape mixture into small balls, roll balls in cocoa, then place in tiny foil or paper cups. 5. The above will be a messy job on your hands-- they will get quite chocolatey; if mixture gets too soft, return it to the fridge to stiffen up again. 6. Keep truffles refrigerated in a covered container; remove from fridge about 30 minutes before serving to take the chill off them. ---------------------------------------------------------------------------
