Prepare the dough by mixing the yeast with warm water, add flour. So the dough looks like before mixing.

Knead the dough using mixer with attachments hooks for at least 7 minutes. It should become smooth and shiny.

The resulting dough cover with a lid and put in a warm place for 3.5 hours. Here's what happened...

Now prepare the dough: in the yeast mixture, add flour and warm water, in which pre-dissolve salt and sugar. Knead about 7 minutes, then add 7 C. softened butter and knead another couple of minutes until smooth.

Remove for 1.5 to 2 hours in a warm place. I say at once that the dough will be quite liquid, so it is better to bake in high forms (e.g., forms for cakes or with high sides, because it is well raised, thereby gaining his "krugovorot"), but I have it turned very liquid, so I had to add about 150 gr. flour.

Next, the formed dough loaf (if structure allows) or decompose to form. I was able to form a loaf, but I put it in a form with high sides! Leave for proofing for 1 hour. Before diving into the oven, make a few nasechek on the test with a sharp knife. On the bottom of the oven, it is desirable to supply the vessel with a small quantity of hot water. Bake about 1 hour at 200 degrees.
