Put the sugar, yeast and salt, mix thoroughly with a whisk.
Add the flour in portions ( it took me 800 g, it may take a little more). Do not clog the dough with flour. Knead the dough thoroughly and put it in a warm place for 2 hours.
I made buns from half of the resulting dough. Divide half of the dough into 8 parts. There are seven parts in the photo. One part has already "got my hands on", and then I remembered about the photo.
What happened next was a test moment for me (in the sense of forming). Next time, I think it will be better. And now it turned out that it did. Each part is rolled out thinly into an oval, cut in half along the length. On each half with a pizza knife (or just a sharp knife), make incisions - ribbons.
Put the filling on the uncut edge.
Roll the preform, starting from the filling side, into a long roll.
Roll the rolls up like a snail. To grease with a yolk. Bake the buns until Golden brown.
Bake the buns until Golden brown. They turned out different for me. I even tried making them with jam. A little flowed, it is better to use thick jam. In General, I liked both the buns and the fun with the dough.
