Peel oranges so that the white skin is completely removed. Remove the fillets from the parting skins with a sharp knife. Squeeze the skins and collect the juice (results in approx. 50 ml). Mix orange juice and collected juice. Stir 5 tablespoons of juice, sugar and sauce powder until smooth. Bring the rest of the juice, cinnamon and aniseed to the boil, stir in the sauce powder, bring to the boil again and simmer for about 1 minute, stirring continuously. Remove from the stove, let it cool down a little.
Carefully fold in the orange filets. Let them cool down. In the meantime bring milk and vanilla sugar to the boil. Add rice, bring to the boil again briefly and let it swell at low heat for 25-30 minutes. Then season to taste with sweetener. Arrange rice and orange compote on 4 plates. Serve decorated with mint and orange slices
