How to dip truffles in chocolate.
Prepare the ganache using my easy dark chocolate truffles recipe. (See tutorial notes for the link.)
Using the small cookie scoop (about 1-inch diameter), scoop the ganache out of the bowl onto a sheet of parchment or wax paper.
If the ganache is quite soft, let it set in the fridge for at least 20 minutes, and then re-shape each truffle with your fingertips to make it more round (try not to handle them too much, to prevent them from melting).
In the top of a double boiler, in a glass bowl over a pan of simmering water, or in the microwave for short (30 second) bursts, melt the chocolate. Stir the chocolate frequently between microwave intervals or while it is on the stove. As soon as the chocolate is melted, remove it from the heat.
Allow the chocolate to set completely. If your house is very warm, you can allow the chocolate to set in the fridge for a maximum of 10 minutes or the freezer for a maximum of 4 minutes.
Note: The chocolate on truffles set in the fridge may crack.
