For kneading and proofing the dough I use a bread maker. In the bucket of the bread maker, pour the sifted flour (first-450 g, depending on the consistency of the dough, you can add flour), salt, sugar, yeast, and mix. Heat the milk and butter until warm, add the vegetable oil, chicken egg, mix with a whisk, put in a bucket. Install the "Dough" program. At the end of the program, we get a bucket with a fragrant, air dough.
