To soften the ice cream, place in the refrigerator for 15 to 20 minutes. You can also store the dough as a log. Wrap it with plastic and roll it into a 5-inch log and chill until ready to use. Then, cut slices off the dough and bake. To speed up tempering the chocolate, you can fill a large bowl with cold water and add a few ice cubes. Once the chocolate is melted, transfer the bowl of melted chocolate to the prepared bowl of cold water and stir the chocolate to quickly bring the temperature down to 80 degrees F.
