• Coarsely chop the chocolate with a serrated knife then transfer to a heatproof bowl.
• Pour the cream into a small saucepan set over medium-high heat and bring just to a boil. Immediately remove from heat and pour over the chopped chocolate. Let stand for 5 to 10 minutes to allow the hot cream to melt the chocolate and to allow the overall temperature to reduce (emulsions form better at 90 to 110°F).
• Whisk the mixture in one direction until smooth and creamy. This may take a little while - just keep whisking until smooth, cohesive, and shiny.
• If using as a glaze, allow to cool for 15 minutes before pouring. If using for truffles, cover and chill for 1 hour, or until solid yet malleable, before scooping into balls. If using as a frosting, allow to chill for 4 hours, or until almost solidified, before using.

Whipped Ganache:

• To make whipped ganache, let a 1:2 ratio ganache chill in the fridge until thickened, about 1 hour. Whip with an electric mixer fitted with the whisk attachment, slowly increasing the speed to medium-high. Whip until light in color and fluffy in texture. Be careful not to overwhip as this can create a grainy texture. If this happens, reheat the ganache in a double boiler, then strain and start again.
