For the nougat pockets, take the puff pastry out of the package and roll it out.
Cut the puff pastry into 2×4 cm rectangles, break the chocolate into ribs.
Place 2 ribs of chocolate on each piece of dough and sprinkle thinly with hazelnuts. Fold the rectangles and brush with yolk.
Bake the nougat pockets in the oven at 180 °C top/bottom heat for about 15 minutes until light.
