For the filling, peel the apples, remove the core, slice into fine wedges and mix with the lemon juice, sugar and spices.
Mix the quark with the egg white, oil, milk and sugar. Mix the flour with the baking powder, spoon into the quark, then knead in.
Roll out the dough about ½ cm thick and cut out squares with sides about 10-12 cm.
Now mix the flour into the apple mixture.
Now distribute the apple mixture over the pieces of dough; Always make sure that at least 1-2 cm of the edge remain free. Fold the pieces of dough together and firmly press the edges shut.
Place the apple turnovers on a baking sheet lined with baking paper. Whisk egg yolks with milk and brush the pockets with it.
Bake at 180 ° C for about 15-20 minutes until golden.
