Sift the flour into a bowl and make a well in the middle. Dissolve the yeast in a little lukewarm water and pour it into the well, cover the liquid yeast with a little flour from the edge. Let the whole thing stand for 5 - 10 minutes.
Add the water, salt and the oil and knead well until the dough loosens from the edge of the bowl. The dough should be pliable and no longer sticky. Cover the dough again and let it rise in a warm place for 30-40 minutes.
Knead the dough again and form 40 g bread rolls out of it, moisten your hands a little if necessary. Place the rolls in a circle in a greased springform pan. However, there should be enough space at the edge as the rolls will still open.
Now brush the bun wreath with a mixture of egg yolk, water and butter, sprinkle with different grains as desired. Cover everything again and let rise in a warm place for 20-30 minutes.
Preheat the oven to 200 ° C (top / bottom heat) and bake the rolls for about 20-25 minutes until the desired brown color. Homemade herb or paprika butter tastes very good with it.
Tip: The rolls can also be baked and frozen for about 10 minutes. Moisten slightly if necessary and finish baking.
