Use the chocolate ganache recipe to make other sorts of truffles as well:
Encase different types of nuts or dried fruits or maraschino cherries in the middle.
Add espresso powder to warm cream and use Kahlua for coffee truffles.
For orange truffles, steep 1 Tablespoon Orange Zest in warm cream for 10 to 15 minutes, strain, and then continue making ganache, using Grand Marnier in place of brandy.
For fruit flavor truffles, use 2 Tablespoon fruit puree or jam instead of alcohol.
Use Calla's Blue Ribbon Caramels for a truffle center, cooking caramel to slightly below soft ball stage to make sure your caramel center isn't too hard.
Experiment with Toriani flavored syrups as well.
Try using different types of alcohol or liqueurs. Or add a hint of cinnamon or nutmeg to your warm cream.
The sky is the limit, so tap into your creativity and have fun!
