This mousse is a light and refreshing dessert, unlike many chocolate mousses, which tend to be heavy and sweet. I have left out the usual dessert whip and the extra sugars and oils that are usually added. You can freeze it if you make it in advance, but I recommend taking it out of the freezer and putting it in the refrigerator about one to two hours before serving.
Tips: You can replace the coffee with 1 tablespoons orange juice or 2 teaspoons of rum.
