Cut the rolls into 2cm thick slices. Mix the milk with the egg yolk, brandy or rum flavor and sugar. Place the bread rolls in a bowl, pour the milk mixture over them and leave to soak.
Lightly beat the egg whites with a fork. Turn the bread rolls in egg white and hazelnuts and fry them brown in clarified butter.
It tastes even better with slices of a yeast plait.
This goes well with vanilla sauce, cinnamon sugar or compote.
