Whip the cream, sugar and vanilla sugar until stiff. Fold in the yoghurt and let it freeze in the ice cream machine (the small version with battery is sufficient).
Let the sugar caramelize until light brown, add 1 tablespoon honey, deglaze with lemon juice and water, simmer. But it still has to remain slightly liquid. Pour the caramel syrup over the strawberries and serve with the ice cream.
When the ice cream comes out of the machine, it is still very soft and needs to be frozen. Before serving, it should be able to thaw in the refrigerator for about 1 hour, then it can be easily shaped into balls.
