Good quality chocolate like Bournville dark chocolate creates a deep and authentic flavor.
Chilling before serving helps in locking in the texture and moisture to keep it fresh while serving.
Fold the ingredients gently and do not mix it vigorously as it can ruin the texture.
Fresh cream has the mild flavor that mixes well with ingredients.
A hint of espresso gives the mousse a caffeine kick and enhances the flavor.
Overheating chocolate can burn it therefore heat it only until it melts.
Skipping chilling time may make mousse soggy, runny, and not airy.
Whipped elements lose their texture and airiness when overmixed.
