Step 1

Coarsely chop the chocolate with a serrated knife then transfer to a heatproof bowl.

Step 2

Pour the cream into a small saucepan set over medium-high heat and bring to a boil. Pour over the chopped chocolate and let stand for 5 to 10 minutes to allow the hot cream to melt the chocolate and to allow the overall temperature to reduce because emulsions form better at 90 to 110°F.

Step 3

Vigorously whisk the mixture in one direction until smooth and creamy. This may take a little while, just keeping whisking. 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 balls. If using as a frosting allow to chill for 4 hours, or until almost solidified, before using.

Step 4

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 just light in color and fluffy in texture. Be careful not to overwhip which will lead to a grainy texture. If this happens, reheat the ganache in a double boiler then strain and start again.
