For the dough, mix flour, 1 pinch of salt and semolina in a bowl. Add 250 ml lukewarm water and knead to a smooth dough with the dough hooks of the hand mixer. Add butter in flakes and knead. Cover the dough with a damp tea towel and set aside
Meanwhile, for the filling, wash the lemon and orange thoroughly and rub dry. Finely grate the peel. Place 1 egg, 1 pinch of salt and sugar in a high mixing bowl and whisk until thick and creamy. Add saffron and stir in. Add cream cheese bit by bit and stir in. Stir in lemon and orange peel
Roll out the dough on a well floured work surface to a thickness of just under 2 mm. Cut out circles (approx. 8 cm Ø). Knead the dough again and roll out and cut out as described until the dough is completely processed
Separate 1 egg. Whisk egg white and egg yolk separately with a fork. Brush the edges of half of the dough circles all around with egg white. Place 1 tablespoon of the filling in the middle of each circle. Place one dough circle each on top as a lid. Press the edges all around with a fork
Place on 2 baking trays lined with baking paper. Brush with egg yolk and bake in the preheated oven (electric oven: 175 °C/ convection oven: 150 °C/ gas: level 2) for 30-35 minutes
Remove from the oven, allow to cool and dust with icing sugar
