Step 4: Cut the Dough, Melt Chocolate
Using your cookie cutter (or shot glass) punch circles into the dough, and put back into the freezer for another 10 minutes. While they are in the freezer, you'll start to melt the chocolate. If you are using a double boiler, set it up and put the chocolate chips and shortening into the top and begin melting. If you are using a microwave, put your ingredients into a heat proof bowl and commence melting, heating at 30 second intervals on high and stirring in between until smooth and without lumps.
