Defrost the raspberries, pass through a sieve. Stir in 50 g sugar and vanillin sugar. Soak gelatine in cold water. Wash lemons thoroughly, rub dry and grate peel. Halve the lemons and squeeze the juice. Separate the eggs. Whisk egg yolk and remaining sugar until white-creamy. Add champagne, lemon juice and zest. Dissolve gelatine over low heat. Take 2 tablespoons of gelatine aside and mix with the raspberry puree. Add a little egg cream to the remaining gelatine, stir the gelatine mixture into the remaining cream and leave to stand in the refrigerator. Whip cream and egg whites separately until stiff. Fold into the egg and champagne cream. Pour the sparkling wine cream in portions into a large dessert bowl, with the raspberry puree in large blobs in between. Leave to set in the refrigerator for approx. 3 hours. Decorate with fresh raspberries as desired
