Break the almond paste into pieces and process in a food processor with the orange paste.
Roll into 10 g balls (use a little cornstarch if needed).
Divide the brioche dough into 35 g portions. Punch down twice then form into balls with an orange almond paste insert in the centre of each.
Arrange 9 filled brioche balls around a 10 cm ring. Remove the ring and let rise for approximately 1½ hour at 26°C. Let rest for 10 minutes at room temperature then brush with the egg wash.
Place a Ø13 cm disc in the centre of the crown to cover then sprinkle around it with ground raw hazelnuts. Bake in a 175°C convection oven for approximately 18 minutes (damper closed). Let cool, gently turn the brioche crown over and fill each ball with 20 g of the cream cheese pastry cream mixture.
Turn over again, place a Ø19 cm disc in the centre of the crown to cover and sprinkle around the edges with icing sugar.
