Mix ingredients and quickly knead a dough. Chill for 1 hour so that the dough is not too soft.
From the cold dough form croissants or pretzels.
Brush with egg yolk-milk-salt mixture and sprinkle with pumpkin seeds and some caraway seeds.
Bake at 180 degrees hot air for about 12-15 minutes (depends on the size of the croissants).
