Prepare a yeast dough with a steamer (fermentation test) from the ingredients.
Steamer: Mix yeast with a little lukewarm milk, 1 teaspoon sugar and enough flour to make a dough. Let this rise in a warm place. Let the finished dough rise for about 1 hour.
Knead the dough well again and form a roll. Cut off even pieces, shape different rolls and cut 2 - 3 small, diagonal lines. Brush the surface with egg and sprinkle with poppy seeds or sesame seeds as desired.
Place the rolls on a greased tray and let rise again briefly.
Preheat the pipe. Slide the tray into the middle rail and place a flat vessel with water in the pipe. Bake at 220 ° C for about 25 minutes.
