Bring the rice with milk and salt to the boil in a saucepan and cover and leave to soak over a low heat for about 20 minutes.
For the sauce, cook the cherries with maple syrup and water in another saucepan for about 2 minutes and allow to cool. Place 14 cherries on kitchen paper. Puree the rest very finely.
Mix the swollen rice with the vanilla sugar, butter and sugar. Let cool a little and fold in the egg yolks.
Form balls out of 1 tablespoon each of rice dough with very well floured hands, fill a drained cherry in the middle and press the flour all around. Bake rice balls in portions in hot oil at 180 ° until golden yellow and drain on paper towels.
Place the rice balls in portions on the sauce, drizzle with eggnog and serve garnished with powdered sugar and mint.
