Bring the elderberries to the boil with water, Glühfix and the stick of cinnamon and simmer.
In the meantime, peel the apple and cut into small pieces or grate. Also chop the plums (if you like, you can peel them). Add the apple and plums after 20 minutes. Simmer for another 10 minutes. Remove the cinnamon stick and the Glühfix. Then mix the custard powder with a little milk. Remove the elderberry roaster from the stove and mix in the mixed pudding powder. Very important: Now the Hollerröster must not boil anymore. Arrange in 2 plates and sweeten to taste. Refine with a dash of Cremefine for whipping. Tastes also very good as a side dish with sweet dumplings.
