Step 1

Fill a medium sized bowl with ice and water.

Step 2

In a second medium sized bowl, add the chocolate. Pour hot coffee over top, and stir until the chocolate is completely melted.

Step 3

Stack the bowl with the chocolate on top of the ice water to cool, and whisk vigorously, for five minutes. It will begin to thicken.

Step 4

Remove from the ice water and stir until you get a fluffy mousse consistency. Transfer to bowls or cups and enjoy immediately, or store in the fridge for up to 4 days. It is also delicious with orange zest on top.
