Soak the gelatine in cold water. Separate eggs. Whisk egg yolk and sugar with the whisk of the hand mixer until thick and creamy. Stir in lemon juice.
Warm the wine. Squeeze the gelatine and dissolve in the hot wine. Pour into the egg yolk mixture while stirring. Chill for about 10 minutes until the cream starts to gel.
Beat the egg white and 1 pinch of salt until stiff. Loosely fold the beaten egg whites into the gelling cream. Pour into dessert glasses and chill for at least 4 hours.
Defrost the raspberries. Puree with vanilla sugar and pass through a fine sieve as desired. Serve wine cream with raspberry sauce.
