Tips for a Perfect Caramel Mousse Cake
Balancing Sweetness
Caramel can be very sweet, so balancing it with a touch of sea salt or dark chocolate helps create depth in flavor.
Ensuring a Smooth Mousse
Whip the cream to soft peaks before folding in the caramel to avoid deflating the mousse.
Preventing a Grainy Caramel
To avoid crystallization, do not stir the sugar while it melts. Instead, gently swirl the pan.
