Use a high-quality chocolate with a cocoa content of at least 70% for the best flavor.
If the ganache becomes too stiff to pipe, warm it slightly by placing the bowl in warm water for a few seconds.
To prevent sticking when rolling, lightly dust your hands with cocoa powder or icing sugar, though chilling the ganache well is the most effective method.
For a decorative touch, you can roll the truffles in crushed nuts, cocoa powder, or edible glitter after the coating sets.
Keep the truffles in an airtight container to maintain freshness and prevent them from absorbing fridge odors.
