For the blueberry layered dessert, place milk, rice pudding and 1 pinch of salt in a saucepan. Scrape out the vanilla pod and add to the milk mixture. Bring everything to the boil briefly, then simmer gently with the lid closed at a moderate temperature for about 30 minutes.
Stir frequently. In the meantime, clean and wash the blueberries. Allow the cooked rice pudding to cool completely and stir in 5 tablespoons of sugar.
Then whip the cream until stiff and fold it into the completely cooled rice pudding. Mix 2 tablespoons of sugar and 1 teaspoon of cinnamon. Now pour the rice pudding into 4 tall glasses, put 1 tsp of cinnamon-sugar mixture on the first layer, then some blueberries.
Continue until all is consumed, ending with blueberries.
