Soak the pudding and plums in rum overnight. The next day, boil in water slightly sweetened with fruit juice. Prepare a dough from the lukewarm cooking stock with the yeast, flour, sugar and spices and finally mix in the fruit. Shape about 4 equal-sized rolls, cover and let rise. Bake at 150 ° for about 50 minutes. Brush with milk while it is still hot.
