Whip the cream with the cream stabilizer and vanilla sugar until stiff, gradually fold in the yogurt.
Clean the raspberries and spread them in a large baking dish (or a smaller baking sheet with a higher rim). Pour the yoghurt-cream mixture over it, then sprinkle cane sugar over the top if you like (we sprinkle an approx. 5 mm thick layer). Cover the pan and place in the fridge overnight until ready to eat.
The cane sugar dissolves easily and combines with the yogurt. Tastes very tasty and refreshing - but take it out of the refrigerator half an hour before consumption so that the food is not too cold and you can better taste the fruit aroma.
Note: Fresh raspberries are of course nicer and not so mushy, but not always available or sometimes of poor quality, in which case it is better to use frozen raspberries.
