01 - Place the finely chopped chocolate in a heatproof bowl.
02 - In a small saucepan, heat the heavy cream until just simmering. Remove from heat and stir in the instant coffee granules until dissolved.

05 - Cover the bowl and refrigerate the ganache for at least 2 hours, or until firm enough to scoop.
