Rasgulla mousse is a light and airy dessert that combines the sweetness of rasgullas with the creaminess of mousse. Start by blending the rasgullas with a little milk to create a smooth puree. In a separate bowl, whip heavy cream until soft peaks form. Gently fold the rasgulla puree into the whipped cream until well combined. Pour the mousse into individual serving glasses or bowls and refrigerate for a few hours until set. Garnish with a rasgulla on top and a sprinkle of grated chocolate. The result is a decadent and flavorful mousse that is sure to impress your family and friends.
