Mix wine (from the package) and 75 ml (5-7 tablespoons) of water in a mixing bowl. Add dessert powder and whisk briefly with the whisks of the hand mixer on a low setting. Then beat at highest setting for approx. 3 minutes until frothy
Whip the cream until stiff and fold in. Spread the cream into 4 dessert glasses, cover and chill for at least 1 hour
Select the raspberries and, except for a few for decoration, puree them. Pass through a fine sieve and mix with vanilla sugar. Spread over the cream. Decorate with remaining raspberries and lemon balm
If you don't want to puree the raspberries extra: simply sweeten them with vanillin sugar and spread them on the wine mousse. This white wine mousse is a nice finish for a light menu. For a more solid menu, a red wine cream is more suitable. Apricots taste better than raspberries
