Story Behind this Recipe
I made this because I didn't have any chocolate mousse!!
If possible, let it chill in the fridge for a firmer and more delicious finish. Let the chocolate cool down after microwaving it in step 1. (Hint: When you mix the chocolate it should leave traces behind.) If you whip the heavy cream while the bowl is still submerged in ice water, the process goes a lot faster!!
