Soak gelatine in cold water. Put apple juice, wine, lemon juice, vanillin sugar and sugar in a pot and heat it up, but do not let it boil. Remove the pot from the heat and stir in the pressed-out gelatine.
Pour the liquid into a flat mould (e.g. an ovenproof dish) rinsed with cold water. Keep cold overnight. Dip the mould briefly in hot water and carefully turn the jelly over onto a kitchen board.
Cut the jelly into cubes. Put milk and cream into a high mixing bowl, add sauce powder and beat at highest speed for about 1 minute. Sprinkle half of the cinnamon. Put the jelly cubes into four dessert glasses.
Add some sauce, sprinkle with remaining cinnamon and serve decorated with lemon balm and lemon slice.
