Soak gelatine in cold water. Warm up apple juice, wine, lemon and sugar slightly. Squeeze out the gelatine and dissolve in it at low heat
Pour the wine and juice mixture into a cold rinsed flat mould. Place in the refrigerator for 5-6 hours (preferably overnight) and allow to set
Before serving, whisk the milk and sauce powder with the whisk of the hand mixer at highest speed for 1 minute until creamy
Turn out the apple-wine-jelly from the mould and dice. Fill jelly cubes into dessert glasses. Pour vanilla sauce over them. Sprinkle some cinnamon on top. Decorate with lemon balm and lemon slices
Instead of gelatine leaves you can also use ground gelatine: swell with 4 tablespoons of cold water, then dissolve in the juice-wine mixture
