Butter dough with milk for buns

Prepare the ingredients. To prepare yeast dough with milk, you need only 7 ingredients: flour, yeast, milk, sugar, salt, chicken eggs, butter.
Let's start preparing the dough with sourdough. Pour warm milk (about 100 ml) into a small container. milk is heated in a microwave oven to a temperature of 36 degrees. You can check the temperature of the milk with your finger, the milk should be well warm, but not hot, the finger should tolerate. Add sugar to the milk, mix so that the sugar dissolves. And then add the yeast and mix again. Yeast loves a warm and sweet environment, but hot liquid can kill them, so we strictly observe the temperature regime. We put the container with sourdough in a warm place, but there is no need to cover it from above. Leave in a warm place for 20 minutes. An air cap of foam will appear on the surface of the liquid, it may fall off when moving, there is nothing wrong with that.
Butter is melted in a water bath and cooled to a warm state, remembers to observe the temperature regime.
In a large bowl, we drive a chicken egg (the number of eggs can be increased, the dough will be more plump), add salt. Beat lightly with a fork, until the mixture is homogeneous. Pour in the melted and cooled butter, sourdough, mix.
We begin to pour in the sifted flour. Be sure to sift the flour, it is better to do it several times to enrich it with oxygen, which contributes to obtaining more airy baking. First, mix the dough with a spoon or whisk, as soon as it becomes difficult to do, dump the dough on the table, add flour and continue to knead the dough until it stops remaining on your hands. You can knead the dough for quite a long time, it likes "hands". Then we put it back in the bowl, cover it with a towel and put it in a warm place for 2 hours. When the dough is suitable, we crumple it and let it rise again. After you do not need to crumple it. It is ready to work and bake.
Bon appetit!
