Variation: Use 12 ounces of semisweet chocolate instead of white chocolate for the ganache base, or split the chocolate base between white and semisweet to create two different flavors.
If the ganache mixture becomes too hard to shape after refrigeration, let it stand at room temperature for 30 minutes until it is firm but pliable.
For best results, use high-quality imported white chocolate. Standard chocolate chips may contain stabilizers that prevent a smooth melt.
When dipping, ensure your hands and tools are dry, as water can cause the chocolate to seize.
