To infuse this mixture with mint, coffee, and other ingredients, follow the instructions in Flavored Ganache, using half the amounts listed.
Bring to a boil in a small saucepan:
Remove from the heat and add:
Stir until most of the chocolate is melted. Cover and let stand for 10 minutes, then stir gently until completely smooth.
For a pourable glaze, let cool at room temperature, stirring occasionally, until the ganache reaches about 85°F. For frosting, let cool further until spreadable. If the ganache becomes too stiff, set the pan in a larger pan of hot water and stir until softened; or remelt and then cool to 85° to 95°F for use as a glaze. This keeps for up to 3 days at room temperature or for up to 1 week refrigerated.
