Wash, clean and quarter the strawberries. Mix in a bowl with sugar and vanillin sugar. Leave to stand for about 1 hour. Drain the fruit and collect the juice. Fill up to 300 ml with grape juice and flavour with lemon juice.
Soak gelatine in plenty of cold water. Fill strawberries in portions into small bowls. Squeeze the gelatine, dissolve, stir into the juice and pour over the fruit. Leave to set in the fridge.
Before serving, whip the cream until stiff, fill into a piping bag with a star-shaped spout and squirt small flowers onto the dessert or add the cream whipped half stiff. Decorate as desired with chocolate flakes.
