Thaw the puff pastry and cut each slice in half = 12 pieces. Place a small rib of nougat chocolate on each square, fold in a corner, press down (works very well with a fork). Whisk the egg with the milk and brush the corners with it. Bake in the oven at approx. 175 ° C for approx. 10 min.
Taste lukewarm and cold.
Tip:
Also works with other chocolate, but best with nougat, which melts slowly and remains somewhat liquid.
